Considerable distance
of the territory to the seas, shield of the Ural mountains from west, direct
neighbourhood with vast steppe regions from the south, and also terrain relief and the features of air masses
circulation determine continental nature of the climate (cold winter with little snow and warm dry summer).
Often returns of chills are characteristic for spring. There is lack of moisture in summer and periodically
recurring droughts. All this makes the territory of the forest-steppe Transurals a zone, risky for
agriculture.
The annual course
of air temperature is sharp and is combined with large variability of winter and spring
months temperatures in different years. The greatest weather instability is observed in the Beginning of
winter - December, in spring months - April, May. January is the coldest month, and the warmest month in
the Transurals is July.
The average annual sum of precipitations on the territory of the region varies within the limits from 470 mms up to
320 mm. The precipitation quantity decreases from northwest to southeast. Summer precipitations
considerably dominate above winter, the maximum is in July and reaches in the west 70-80 mms, in the
southeast 50-60 mm.
Winter in Kurgan region
is the longest of all seasons. The period with a steady snow cover oscillates from
150 to 160 days. The altitude of the snow cover on average reaches 38 cm in north and 26 cm in south,
but it considerably oscillates in different years. The snow cover is set in at the end of the first and
in the Beginning of the second decade of November. In the Beginning of April the winter cover begins to
disappear, and to the end of the second decade the snow finally descends in the all territory of the region.
The flat nature
of terrain and continental climate promotes constant motion of air masses. Winds of
western and southwest directions dominate. Average speed of air masses movement is 4-5 meters per second,
but freqeuntly the strength of sharp gusty winds reaches 15-20 meters per second. The most quiet are
December and January, the most windy are March, April, May, June.
The atmospheric pressure
changes according to the air temperature and passing of cyclones and anticyclones.
When cyclone passes, the pressure reduces, and when anticyclone passes it increases. On the average the
year pressure makes 756.6 mm. The lowest pressure is marked in a warm season (up to 749.4 mm on the
average and up to 721.6 mm minimum). In winter the pressure increases on average up to 764.5 mm and
maximum up to 791.5 mm.
