Day-to-day changes in air temperature in the southern part of the Russian Far East

Day-to-day changes in air temperature for cities in the southern part of the Russian Far East experience a noticeable annual dynamics with its maximum in winter and minimum values in summer, and a noticeable increase in May as compared to neighboring months. The summer minimum in Vladivostok is slightly smaller than in Khabarovsk, and these values are two times less than maximum values in winter. The cold period maximum is most pronounced in Vladivostok from November to February. In Khabarovsk, the maximum critical temperature changes (more than 5°(C) are observed during the winter period in December and January; the fewest such days are in August. A sharp shift in temperatures is typical for the transition period from September to October, when the number of days with a significant change in the inter-day temperature is tripled. The off-season critical temperature changes dynamics in Vladivostok is the same, but the absolute value of the maxima is twice as high as in Khabarovsk. This is due to the maritime climate of Vladivostok, active cyclonic activity, accompanied by constant temperature changes in winter.
