Kalendarz pogód dla Hornsundu podczas wyprawy założycielskiej 1957/58

The Weather calendar for the Founding Expedition Hornsund 1957/58 is conceived using four meteorological elements: air temperature, wind speed, precipitation and relative humidity. Each of those variables is classified as system consisting of three classes, except precipitation, which comprises two classes. First class contains values below 25% percentile (under normal), third contains values above 75% percentile (above normal) of meteorological elements under consideration. Second class contains values between first and third class (normal). Precipitation is classified using two-class system, which describes if precipitation occurs or not. These rules give 3 groups, 9 subgroups, 18 classes and 54 types of weather. All statistics are presented for three periods: 12 months from August 1957 to July 1958, polar night and polar day. In all these periods groups of weather with normal temperature (2WOF) dominate. Typical weather subgroups are those of low temperature and weak wind (11OF) as well as normal temperature with weak (21OF) and moderate wind (22OF). Prevailing weather class is cool weather with weak wind and without precipitation (110F). Characteristic attribute of Hornsund area is weather with low humidity (TWO1).
