Climatology (from Greek κλίμα, klima, "place, zone"; and -λογία, -logia) or climate science is the scientific study of climate, scientifically defined as weather conditions averaged over a period of time. This modern field of study is regarded as a branch of the atmospheric sciences and a subfield of physical geography, which is one of the Earth sciences. New Data on Earth's Climate History New data obtained from an Arctic drilling expedition indicates that about 49 million years ago, the Arctic was green, with fresh surface water and ferns.
Because on J , James Hansen, a climate scientist at NASA, appeared before a US Senate hearing with a warning for the world. In , the IPCC released its third assessment report. This one was more certain and spelt out the consequences of climate change this century. Climate data for Uunarteq (north), elevation: 41 m, normals; Month Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Year Average high °C (°F)State: Kingdom of Denmark.
Each EASE-Grid chart for weekly charts and climatology products after consists of five layers of information: total ice concentration, multiyear (MY) ice concentration, first-year (FY) ice concentration, thin ice concentration, and landfast ice (pixel-by-pixel yes/no), following a convention established with the AARI Day Arctic Ocean. Simulated ice thickness agrees well with direct measurements made during severe and normal winters. Simulated snow thickness has been overestimated in comparison with the measurements. The model does not take into account the snow carried away by winds and also the snow that has been compressed (the forming of the so-called snow ice).

Climate simulations in a global coupled model are investigatedCited by: The prediction of future changes in Arctic sea ice, and consequent effects on the ocean 12 and atmosphere 2, relies on global climate models Ice thickness climatology reproducing changes in ice thickness Cited by: Ice Climatology is a long-term view of ice conditions observations and measurements over a given geographic water region.
It can be used to identify averages, trends and record conditions. It is very important to monitor and archive sea ice conditions of Canadian waters every year. Climatology Free pdf books from Bookyards, one of the world's first online libraries to offer ebooks to be downloaded for free.
In response to a prescribed surface climatology, the ice-sheet model computes surface mass balance, basal meltrates, ice thickness, surface elevation and ice velocities on a ∼ 1 × 1 km grid.
Although this grid only coarsely resolves Langjökull's outlet glaciers (Fig. 1), grid size is limited by the shallow-ice approximation made to the Cited by: Ice concentration, defined as the percent areal coverage of ice, is calculated at each grid square through the NASA Team algorithm (Gloersen et al.
), and ice extent is calculated as the sum of the area of grid squares with ice concentration at least 15% [as in Parkinson et al. (), Zwally et al. (), Meier et al. (), and numerous Cited by: In order to control growth of the sea ice thickness, the sea ice thickness is limited to 10 m.
During the ½ × CO 2 integration presented here, whenever the sea ice thickness exceeds this critical value, the thickness is set to 10 m. The difference between the original thickness and 10 m is converted into an equivalent amount of heat and water Cited by: Arctic Report Card: Only 7 percent of the ice cover at the end of winter was old, thick ice December 9, In Marchthick, multi-year ice comprised 26 percent of the Arctic's ice pack.
A series of contemporary experiments are initiated to validate the model against the present ice cover across Iceland. Forcing the model from ice-free conditions with the – (reference) climatology yields a good simulation of all the ice masses except for Vatnajökull, where the model falls well short of its present by: Thermal characteristics and impact of climate change on mountain permafrost in Iceland Herman Farbrot,1 Bernd Etzelmu¨ller,1 Thomas V.

Standard Normals are official normals computed for the World Meteorological Organization based on submission of data by its members.
Standard normals are computed every thirty years (e.g.etc.). Sea ice thickness is, perhaps, the most important climate state variable that is currently poorly observed, poorly documented, and poorly archived. We as a community can do much better and a unified sea ice thickness data set is an important step forward.COVID Resources.

The model also does well at reproducing snow depth on-ice normals with a MAD of less than 3 cm. However, for both simulated ice thickness and snow depth normals, the results suggest that the model Figure 1: Location of study area.
