Understanding Antarctic Peninsula precipitation distribution and variability using a numerical weather prediction model
Daily precipitation fields and annual means from the European Centre for Medium-range Weather Forecasts re-analysis exercise are used to examine the distribution and variability of precipitation across the Antarctic Peninsula. The annual mean precipitation field from the model agrees well with the a...

Daily precipitation fields and annual means from the European Centre for Medium-range Weather Forecasts re-analysis exercise are used to examine the distribution and variability of precipitation across the Antarctic Peninsula.

The Peninsula is shown to be a very effective barrier to the zonal movement of precipitati ng weather systems, which results in quite different atmospheric flow regimes being responsible [or significant precipitation events on either side of the divide. Frontal depressions are the primary source of large daily snowfall totals on both sides of the Peninsula.
