Unstructured Grid Antarctic Weather Forecast System
Weather forecasting in Antarctica is essential for US Antarctic Program (USAP) operations. However, forecasting in this region is extremely difficult both because the observational and modeling tools available are inadequate and because our understanding of the science behind the meteorology of Antarctica is incomplete. The weather of Antarctica is dominated by three factors: (1) the polar high...
متن کاملSummer weather conditions at projected LARISSA drill sites, Antarctic Peninsula, based on recent AMPS archive
Drilling operations are expected to be carried out during the Southern Hemisphere summer 2009-2010 in the Antarctic Peninsula as part of the LARsen Ice Shelf System, Antarctica (LARISSA) program. To support upcoming field operations, we present a short study of typical weather conditions that might be expected at the projected drilling sites. We used weather forecasts from the Antarctic Mesosca...
متن کاملGlove and mitten protection in extreme cold weather: an Antarctic study
Background Myths, misconceptions and a general lack of information surround the use of gloves and mittens in extreme cold environments. Objective This study assessed how well an assortment of gloves and mittens performed in a very cold environment. Methods A convenience sample of gloves and mittens were tested in Antarctica during the winter of 2016 using a calibrated thermometer (range: -148°F...
متن کاملAntarctic Space Weather Data Managed by IPS Radio and Space Services of Australia
Ionospheric Prediction Services (IPS) has an extensive collection of data from Antarctic field instruments, the oldest being ionospheric recordings from the 1950s. Its sensor network (IPSNET) spans Australasia and Antarctica collecting information on space weather. In Antarctica, sensors include ionosondes, magnetometers, riometers, and cosmic ray detectors. The (mostly) real-time data from the...
متن کاملDemographic effects of extreme weather events: snow storms, breeding success, and population growth rate in a long-lived Antarctic seabird
Weather extremes are one important element of ongoing climate change, but their impacts are poorly understood because they are, by definition, rare events. If the frequency and severity of extreme weather events increase, there is an urgent need to understand and predict the ecological consequences of such events. In this study, we aimed to quantify the effects of snow storms on nest survival i...
