The article analyses the air temperature characteristics of the winter season in Koszalin from 1850 to 2010. The trends of changes have been determined. In addition, the frequency of thermal anomalies has been shown. The thermal classification of Lorenc has been adopted for this study. The relationship between the North Atlantic Oscillation and the air temperature in winter seasons has been estimated.
The basic features of annual course of air temperature (differentiated between the particular months and seasons) along with air temperature variations during the period between 1950 and 2009 together with the trends of changes are presented. In addition the dependence of air temperature on North Atlantic Oscillation (NAO) is exhibited.
This study is an attempt to provide a comprehensive and synthetic characterisation of Słupsk climate based on a homogeneous series of daily measurements covering the longest possible period. Apart from the temperature and precipitation profiles derived from a 58-year examination record (1950-2007), the climate analysis also presents the distribution of other key weather components (atmospheric pressure,...
The paper presents an analysis of the extreme precipitation recorded in north-western Poland between 1951 and 1995. The author of the present paper selected a day with a maximal twenty-fourhour precipitation sum out of each month. The author also selected intervals characterized by specific twenty-four-hour values: 0.1-9.9 mm, 10.0-19.9 mm, 20.0-29.9 mm, 30.0-49.9 mm, 50.0-99.9 mm and ≥100 mm. The...
This paper presents the basic features of annual course of air temperatures and the sum of precipitation (diversification of temperatures and precipitation in separate months and seasons). The paper also determines air temperature and precipitation fluctuations in 1861-2007 and the trends of changes. Finally, the relations between the North Atlantic Oscillation (NAO) and the air temperatures and precipitation...
The present paper concentrates on the basic features of an annual precipitation course (monthly, seasonal and annual sums) registered between 1861-2000. The paper also defines an amount of precipitation sums’ deviations from the many years’ average, factor of monthly precipitation sums’ changeability and trends of their changes. The characteristics of the annual precipitation sums in an annual course...
The authors of the present paper made an attempt to determine frequency of average, dry and wet periods for months, seasons, half-years and years. Additionally a comparison of data recorded dur-ing 140 years allows to check the structure of excessively wet and excessively dry years’ patterns. The present paper is based on the Z. Kaczorowska’s classification (1962).
The aim of this work is the analysis of precipitation totals and frequency in the north-west of Po-land depending on the type of atmospheric circulation. Heavy rains are of remarkable importance for agriculture, forestry, weather forecasts etc. In the north-west of Poland percentage of heavy rains in the annual total is great (nearly 41,2%) with the average annual value 7,3%. The basis for the analysis...
The purpose of the study reported was to determine the dependence of the occurrence of high daily precipitation sums (≥10 mm) upon the atmospheric circulation types (as classified according to Osuchowska-Klein) within the area of the north-western Poland. The source data are constituted by the daily precipitation sums for the period 1961-1980, measured at 185 precipitation gauges. The shares of the...
