Primorye's winter     In regard to precipitation (500-900 mm per annum), Primorye belongs to the zone of sufficiently high humidification. Maximum precipitation (800-900 mm) occurs on the western coast of Peter the Great Bay and in the mountains of Sikhote Alin on the eastern and western slopes. The annual precipitation there surpasses evaporativity. The districts of Hanka Plain, where the amount of precipitation ranges from 500 to 600 mm, and evaporativity in some places tops that amount, are less humidified, especially in spring and summer.
     Primorye’s humidification regime is characterized by pronounced seasonal fluctuation. In winter, transfer of moisture from the warmer ocean to the continent is minimal. For that reason, even over most of the coastal zone, winter is characterized by little clouds and least annual precipitation. About 70 percent of the annual precipitation occur in summer and fall, and 10 percent in winter. Most cloudy days occur in summer.  Overall precipitation increases from west to northeast and southeast. Twenty percent of annual precipitation falls in solid form. The earliest snow appears in the first ten days of December on the peaks of Sikhote Alin. The average number of snowy days in the foothills and peaks of Sikhote Alin  range from 140 to 210, in Hanka Plain from 85 to 140, and on the coast of Japan Sea from 45 days in the south to 140 days in the north.
