Key

Data for this table were taken from the archive of the British Antarctic Society. They are based on hourly observations taken at 00 hour UTC between November 9 and December 9 for a variable number of years

POR

Period of record, or the length of time in years for which meteorological data are available.

Ave. Temp.

The mean of the temperatures at 00 UTC between November 9 and December 9 for the period of record, in degrees Celsius. Many values are missing from Antarctic stations, but most means are based on at least 90 reports.

Min. Temp.

The lowest temperature (C) in the data collected during the period of record.

Max. Temp.

The highest temperature (C) in the data collected during the period of record.

Ave. Wind Chill

Mean wind chill (C) calculated using the new wind chill formula developed by Environment Canada and U. S. National Weather Service. The formula can be found at http://windchill.ec.gc.ca.

Min. Wind Chill

Coldest wind chill the lowest wind chill value (C) calculated during the period of record.

Ave. Wind Speed

The mean wind speed (km/h) for the period of record.

Max. Wind Speed

The greatest wind speed (km/h) for the period of record.

Prevail. Wind Direction

Prevailing wind direction the most common wind direction or directions in the record.

Average Cloud Cover

Mean cloud amount in tenths in the record. Cloud observations are recorded in octas (eighths); these values are converted from those records. Obscured conditions are included in the overcast category. These make up only a small percentage of the observations.

Most Frequent Cloud Cover

The cloud amount that had the highest frequency in the period of record.

Eclipse Observing Probability

The summed product of the cloud amount times its frequency. It assumes that the Sun is high (above 45°) and that all observed cloud is opaque. It provides a good comparison among observing stations.
