CLIMATE DISTINCTIONS THROUGHOUT PRIMORYE AND APPISAL
Sikhote Alin separates Primorye
into western and eastern districts, substantially differing in climate.
In the western districts, the climate is more continental, with cold winter
and hot summer. In the eastern districts, the winter is warmer, and summer
foggy. Primorye is considerably extended (for over 900 km) from the northwest
to the southeast and this causes the difference in amount of evaporation
and other climatic factors. The sum total of average temperatures for the
period of active vegetation of most farming crops, the period with mean
daily temperatures exceeding 10oC,
is applied most frequently to characterize PrimoryeТs heat resources.
In Primorye, the average duration
of the period between dates of stable air temperature (+10oC)
varies from 114 to 159 days, and the sum totals of temperatures during
that period from 1800o
in the northern, coastal and mountain areas to 2650o
within the bounds of Hanka valley, i.e. exactly the same as in the south
of Ukraine and in Kuban region. The abundance of moisture in summer, and
the high sum totals of active temperatures, are conducive to ripening in
Primorye not only of cultures generally common to Russia, but also of rice,
soybeans, grapes and other heat-loving crops.
PrimoryeТs climate is favorable
for developing various branches of the economy, resorts, sanatoriums, tourism
and sports. Unfavorable aspects involve abundant torrential rains, when
30 percent of annual precipitation may fall out, and also dry winds in
the Hanka lowland.
