Sc. Marit Berger will present her licentiate thesis entitled "Modelling the early to mid-Holocene Arctic climate" in Kollegiesalen, Brinellv?gen 8, Kungliga tekniska h?gskolan (KTH) Opponent: Prof. Rodrigo Caballero, MISU, Stockholm University Abstract In the recent past it has become evident that the Earth's climate is changing, and that human activity play a significant role in these changes. One of the regions where the ongoing climate change has been most evident is in the Arctic: the surface temperature has increased twice as much in this region as compared to the global average, in addition, a significant decline in the Arctic sea-ice extent has been observed in the past decades. Climate model studies of past climates are important tools to understand the ongoing climate change and how the Earth's climate may respond to changes in the forcing. This thesis includes studies of the Arctic climate in simulations of the early and mid-Holocene, 9 000 and 6 000 years before present. Changes in the Earth's orbital parameters resulted in increased summer insolation as compared to present day, especially at high northern latitudes. Geological data imply that the surface temperatures in the early to mid Holocene were similar to those projected for the near future. In addition, the geological data implies that the Arctic sea ice cover was significantly reduced in this period. This makes the early to mid-Holocene an interesting period to study with respect to the changes observed in the region at present. Several model studies of the mid-Holocene have been performed through the Paleoclimate Modeling Intercomparison Project (PMIP1 to PMIP3). The simulations have been performed with climate models of varying complexity, from atmosphere-only models in the first phase to fully coupled models with the same resolution as used for future climate simulations in the third phase. The first part of this thesis investigates the simulated sea ice in the pre-industrial and mid-Holocene simulations included in the PMIP2 and PMIP3 ensemble. As the complexity of the models increases, the models simulate smaller extents and thinner sea ice in the Arctic; the sea-ice extent suggested by the proxy data for the mid-Holocene is however not reproduced by the majority of the models. One possible explanation for the discrepancy between the simulated and reconstructed Arctic sea ice extent is missing or inadequate representations of important processes. The representation of atmospheric aerosol direct and indirect effects in past climates is a candidate process. Previous studies of deeper time periods have concluded that the representation of the direct and indirect effects of the atmospheric aerosols can influence the simulated climates, and reduce the equator to pole temperature gradient in past warm climates, in better agreement with reconstructions. The second part of the thesis investigates the influence of aerosol on the early Holocene climate. The indirect effect of reduced aerosol concentrations as compared to the present day is found to cause an amplification of the warming, especially in the Arctic region. A better agreement with reconstructed Arctic sea ice extent is thus achieved. All are most welcome!

Message-ID: Dear Bolin Centre Scientists, As you are well aware the IPCC climate report will be made public on the 27 September and this will hopefully be very hot in the media. IPCC will discuss the text in the week leading up to the 27, and are thus forbidden to talk to the media during this time. Media will be looking for other sources of information about climate and this is of course a golden opportunity for us! We are putting together a media plan, and would like some input from you: Have you or do you know that you are going to be visible in the media somehow in connection with the IPCC report? Please send me an email about it stating who, how, where, when, what ?? If you have some resent research results that can be linked to the IPCC report in some way, we would gladly help you to do a press release about it right now! If you have some great ideas of public outreach in connection to the IPCC report, please send me an email about it. Some general advice: It is a very good thing to practice stating what you do research on in one or two sentences (within a few seconds). This harder than it sounds! It is equally very good to think of answers in advance to FAQ:s from climate skeptics. If you are contacted by the media, please Do not turn them down, but answer them or send them to a colleague that you know will answer them well Please answer journalists in such a way that the interests and concerns of the common man is in focus. ("This is very important because if affects the common man in XXX way?") Please mention you affiliation as "NN at the Bolin Centre for Climate Research, Stockholm University" or "NN at the Bolin Centre for Climate Research, SMHI" or "NN at the Bolin Centre for Climate Research, KTH" Please send me an email about it I'll include a pdf with some general advice of how to do presentations.

This is due to a combination of factors: Polar lows form over data sparse regions, they are an order of magnitude smaller than synoptic-scale cyclones, and they are partly driven by moist convection, which is often inadequately treated in operational NWP models. Polar lows form in connection with marine cold air outbreaks over relatively warm seas during the winter, e.g., over the Norwegian Sea, the Barents Sea, the Denmark Strait and the Sea of Okhotsk, as well as near Antarctica. > In this talk, we will present some highlights from a 3-week aircraft-based measurement campaign out of And?ya (69?N, 16?E) in 2008, as well as its follow-up including the development of a limited area ensemble prediction system at the Norwegian Meteorological Institute. During the campaign, which was a part of the IPY-THORPEX project (Kristj?nsson et al., 2011; BAMS), three significant polar low developments were captured by dropsonde measurements and LIDAR retrievals. In one case (3-4 March), the full life cycle of a polar low over the Norwegian Sea was captured by three consecutive flights. These measurements represent a unique legacy for polar low research by: a) Mapping the three-dimensional structures of a polar low at three different stages of development; b) Serving as a test-bed for validation of model simulations in an otherwise data-sparse region. > > Another polar low that formed in almost the same area over the Norwegian Sea two weeks later (16-17 March) was much more poorly predicted, with many of the operational models at the time placing the polar low several hundred kilometers too far southwest. We will present results addressing possible causes of this difference in predictability. > > We will summarize how the campaign data have contributed to new knowledge about polar lows, as well as to new forecasting tools, and we will identify the main remaining challenges. > > Welcome! > -- > V?nliga h?lsningar, > ?sa ?man > > Meteorologiska institutionen > Stockholms universitet > 08-164332 > www.misu.su.se > _______________________________________________ > Seminarie-at-misu.su.se mailing list > Seminarie-at-misu.su.se at lists.su.se > https://lists.su.se/mailman/listinfo/seminarie-at-misu.su.se -------------- next part -------------- An HTML attachment was scrubbed...

Prof. Michael Evan Goodsite from Aarhus university (see bio below) is visiting ITM this Wednesday 25.9., and as part of this visit he will give a semninar on his recent work on mercury deposition based on environmental archives (see the details of the talk below) in the William-Olssonsalen at 10 am. Welcome! Ilona ************************************************************************************************* Michael Goodsite*, Peter M. Outridge and Hamed Sanei. AU Herning, Aarhus University, Herning, Denmark. *Presenter:MichaelG at hih.au.dk This talk will present a review by our team recently published in Science of the Total Environment. The review compares the reconstruction of atmospheric Hg deposition rates and historical trends over recent decades in the Arctic, inferred from Hg profiles in natural archives such as lake and marine sediments, peat bogs and glacial firn (permanent snowpack), against those predicted by three state-of-the-art atmospheric models based on global Hg emission inventories from 1990 onwards. Model veracity was first tested against atmospheric Hg measurements. Most of the natural archive and atmospheric data came from the Canadian-Greenland sectors of the Arctic, whereas spatial coverage was poor in other regions. In general, for the Canadian-Greenland Arctic, models provided good agreement with atmospheric gaseous elemental Hg (GEM) concentrations and trends measured instrumentally. However, there are few instrumented deposition data with which to test the model estimates of Hg deposition, and these data suggest models over-estimated deposition fluxes under Arctic conditions. Reconstructe d GEM data from glacial firn on Greenland Summit showed the best agreement with the known decline in global Hg emissions after about 1980, and were corroborated by archived aerosol filter data from Resolute, Nunavut. The relatively stable or slowly declining firn and model GEM trends after 1990 were also corroborated by real-time instrument measurements at Alert, Nunavut, after 1995. However, Hg fluxes and trends in northern Canadian lake sediments and a southern Greenland peat bog did not exhibit good agreement with model predictions of atmospheric deposition since 1990, the Greenland firn GEM record, direct GEM measurements, or trends in global emissions since 1980. Various explanations are proposed to account for these discrepancies between atmosphere and archives, including problems with the accuracy of archive chronologies, climate-driven changes in Hg transfer rates from air to catchments, waters and subsequently into sediments, and post-depositional diagenesis in peat bogs. However, no general consensus in the scientific community has been achieved. Lastly, a quick introduction to the research that we at AU Herning are doing in cities and the Arctic and will be presented.

Message-ID: Dear colleagues, Tomorrow (yes, the same day as the IPCC release!) we would like to invite all interested to KTH for a licentiate seminar. The seminar starts at 10.15 a.m. and the seminar room is located in the Red Cross Hospital which was taken over by KTH. Most welcome! Jenny September 27, at 10.15 a.m. M. Sc. Marit Berger will present her licentiate thesis entitled "Modelling the early to mid-Holocene Arctic climate" in Kollegiesalen, Brinellv?gen 8, Kungliga tekniska h?gskolan (KTH) Opponent: Prof. Rodrigo Caballero, MISU, Stockholm University Abstract In the recent past it has become evident that the Earth's climate is changing, and that human activity play a significant role in these changes. One of the regions where the ongoing climate change has been most evident is in the Arctic: the surface temperature has increased twice as much in this region as compared to the global average, in addition, a significant decline in the Arctic sea-ice extent has been observed in the past decades. Climate model studies of past climates are important tools to understand the ongoing climate change and how the Earth's climate may respond to changes in the forcing. This thesis includes studies of the Arctic climate in simulations of the early and mid-Holocene, 9 000 and 6 000 years before present. Changes in the Earth's orbital parameters resulted in increased summer insolation as compared to present day, especially at high northern latitudes. Geological data imply that the surface temperatures in the early to mid Holocene were similar to those projected for the near future. In addition, the geological data implies that the Arctic sea ice cover was significantly reduced in this period. This makes the early to mid-Holocene an interesting period to study with respect to the changes observed in the region at present. Several model studies of the mid-Holocene have been performed through the Paleoclimate Modeling Intercomparison Project (PMIP1 to PMIP3). The simulations have been performed with climate models of varying complexity, from atmosphere-only models in the first phase to fully coupled models with the same resolution as used for future climate simulations in the third phase. The first part of this thesis investigates the simulated sea ice in the pre-industrial and mid-Holocene simulations included in the PMIP2 and PMIP3 ensemble. As the complexity of the models increases, the models simulate smaller extents and thinner sea ice in the Arctic; the sea-ice extent suggested by the proxy data for the mid-Holocene is however not reproduced by the majority of the models. One possible explanation for the discrepancy between the simulated and reconstructed Arctic sea ice extent is missing or inadequate representations of important processes. The representation of atmospheric aerosol direct and indirect effects in past climates is a candidate process. Previous studies of deeper time periods have concluded that the representation of the direct and indirect effects of the atmospheric aerosols can influence the simulated climates, and reduce the equator to pole temperature gradient in past warm climates, in better agreement with reconstructions. The second part of the thesis investigates the influence of aerosol on the early Holocene climate. The indirect effect of reduced aerosol concentrations as compared to the present day is found to cause an amplification of the warming, especially in the Arctic region. A better agreement with reconstructed Arctic sea ice extent is thus achieved. ********************************************* Jenny Brandefelt Ph.D Dynamic meteorology Climate expert Swedish Nuclear Fuel and Waste Management Company (SKB) Research and safety assessment Address: Blekholmstorget 30, Box 250, 101 24 Stockholm, Sweden Phone: +46 8 579 387 53 Mobile phone: +46 70 253 34 50 Affiliated faculty Kungliga tekniska h?gskolan (KTH) Mechanics department Stockholm, Sweden http://www.mech.kth.se/~jenny ********************************************* -------------- next part -------------- An HTML attachment was scrubbed...

This pattern appears to be consistent with simulations under increasing greenhouse gas emission scenarios for the end of the 21st century. There is, however, no scientific consensus on the existence of long-term trends in storm statistics since the 1880s or earlier. In the absence of reliable wind observations, long-term storminess is usually derived from indices based on more homogeneous pressure data or quasi-homogeneous reanalysis wind fields. As shown by previous analysis (Krueger et al., 2013), low-frequency variations and trends of geostrophic wind indices are not consistent with the output of the 20th Century Reanalysis (20CR) since 1871. This is most likely due to spurious trends caused by a varying number of assimilated observations in 20CR i.e. in data sparse regions. In this talk, the analog-method is introduced as an alternative strategy to derive physically consistent meteorological fields from sparse observation data (Schenk and Zorita, 2012). Storminess derived from the reconstructed daily wind fields since 1850 are compared with geostrophic wind indices, a storm flood index and the 20CR output. While the analysis of deep cyclones (< 980 hPa) suggests an unprecedented high spatial impact of extreme cyclones in recent decades, annual wind statistics since 1850 point towards a rather stationary wind climate in agreement with global model simulations of the last millennium. The results of the analog-reconstruction are consistent with geostrophic wind indices confirming also that 20CR cannot be used for the evaluation of long-term trends since 1871 over data sparse regions.
