Climatology
Continental climates exist where cold air masses infiltrate during the winter and warm air masses form in summer under conditions of high sun and long days. Places with continental climates are as a rule either far from any moderating effects of oceans (examples: Omaha, Nebraska, USA and Kazan, Russia) or are so situated that prevailing winds tend to head offshore (example: Vladivostok, Russia). Such regions get quite warm in the summer, achieving temperatures characteristic of tropical climates but are much colder than any other climates of similar latitude in the winter.
