Climatological tables for the site of the expeditions base at Brittania Sø and the station on the inland-ice "Northice"

Abstract

This paper consists mainly of climatological tables compiled from the meteorological observations made by the British North Greenland Expedition 1952- 54 over a period of about 20 months at the two stations Britannia S0 (approx. 77° N. 23° W., alt. 231 m) and at "Northice" (approx. 78° N. 39° W. alt 2345 m).

A general description is made of the site of the meteorological stations and of the surrounding topography. The tables for each meteorological element are accompanied by a brief description of the instruments used, the methods of calibration, corrections applied etc. The tables include monthly means of the following meteorological elements: wind speed, temperature at each synoptic hour, maximum and minimum temperatures, relative humidity and vapour pressure, pressure at station level, amounts of cloud and low cloud at the synoptic hours. The extreme values of temperature, pressure, relative humidity and vapour pressure are also given.

For each month is given the total precipitation, the number of days of rain, snow and gale.

The frequency tables show the diurnal variation of wind, cloud amount and visibility, the variation of wind speed with direction, the frequency of maximum temperature, minimum temperature and wind chill in certain ranges and the variation of the state of ground.
