Based on Kraków's measurement series of air temperature in the 20th century an attempt was made to analyse the winter season by means of some criteria which are important for the thermal conditions which-in turn-influence natural processes
and phenomena. The first day with mean daily air temperature
days and sums of frost. Special attention was paid to extreme winters because of their thermal conditions as well as their frequency and variability.

In order to represent the weather distribution of Japan related to the winter monsoon, the modified method of Jacob's synoptic climatology was adopted. Airflow patterns were decided for each of five regions in Japan. - (SGA)
Spatial variability of midtropospheric circulation patterns and associated surface climate in the United States during ENSO winters

Atmospheric circulation ; Climatic variation ; Precipitation ; Temperature ; Troposphere ; United States ; Weather type ; Winter
This study identifies the dominant synoptic circulation patterns and associated temperature and precipitation departures that occur during ENSO winters. Using standardized departures of 500 mbar heights over North America and the North Pacific Ocean
, a subjective classification of the anomaly maps for winter months identified as warm ENSO events identifies three basic categories of 500 mbar standardized anomaly patterns.

Atmospheric circulation ; El Niño ; India ; Ocean atmosphere interaction ; Precipitation ; Surface temperature ; Teleconnection ; Winter
Monthly precipitation data are assembled to analyze the impact of global teleconnections, namely ENSO, PDO, and local sea surface temperature (SSTs) on winter rainfall across the Indian subcontinent from 1925 to 1998. Canonical correlation analysis
reveals one statistically significant vector for the precipitation occurring over the subcontinent and one for the predictor variables. The results of the study will be useful for greater efficiency in the forecasting of winter precipitation.

In this study the relationship between the Arctic Oscillation (AO) and climate in China in boreal winter are investigated. Correlation analysis for the last 41 years shows that the winter temperature and precipitation in China change in phase
Patterns of winter dessication in krummholz forms of Abies lasiocarpa at treeline sites in Glacier National Park, Montana, USA

The objectives of this research are to : quantify the amount of winter dessication that occurred at treeline sites in Glacier National Park, Montana, during the winter of 1998/1999; determine if the variability in winter dessication between
climatic factors may be responsible for inter-annual winter dessication variability.
Winter Atlantic climate and snowfall in the south and central Appalachians

Winter snowfall over much of the south and central Appalachian region shows a significant inverse association with a winter index of the North Atlantic Oscillation (NAO) teleconnection pattern. The snowiest winters coincide with the negative phase

This paper attempts an evaluation of winter thermal differentiation in the Carpathian altitudinal profile in relation to some external and internal factors of the montane climatic system. Mean monthly, mean daily and daily maximum air temperature
were taken, for 3 stations representing different altitudinal climatic zones, in the period 1961/62-1990/91. The variability of the dates of winter commencement and end, winter duration and thermal indices were analysed, as was the relation between
Extreme summer and winter temperatures in the Czech Lands after A.D. 1500 and their Central European context

Air temperature ; Climate ; Climatic trend ; Climatic variability ; Czech Republic ; Summer ; Temperature ; Time series ; Winter
Extremely cold/mild winters (DJF) and extremely cold/warm summers (JJA) in the Czech Lands were derived from series of temperature indices based on documentary evidence (1500–1854) and from series of air temperatures measured at the Prague
-Klementinum station (1771–2007) over the past 500 years. Altogether 24 cold winters, 23 mild winters, 18 cold summers and 21 warm summers emerged. Czech extremes were compared with the Central European temperature series and series of documentary-based

The aim of this paper is to analyze the interannual variability which characterizes the late-winter surface air temperature in mid-latitude Europe, 45-60°N, and discuss its causes. The AA. analyze the interannual variability at its extreme
by comparing the warm-winter/early-spring of 1989/90 with the opposite scenario in 1995/96. They examine the influence of maritime-air advection in raising the winter air temperature in Europe.
