What is a defining characteristic of a continental climate regarding its seasons?

A defining characteristic of a continental climate is indeed the presence of short summers and long winters. This type of climate is typically found in regions located away from large bodies of water, which results in a greater temperature variation between seasons. In the summer, temperatures can rise significantly, but these warm periods are relatively brief. In contrast, winters can be quite harsh and prolonged, leading to the classification of continental climates as having a marked seasonal contrast.

The distinction between these seasons is pronounced, with a significant chill during winter months and a warm but limited summer season. This fluctuation is contrasted with other climates, where summers may be long and mild or temperatures remain even year-round. High humidity is not a defining characteristic of continental climates, as they tend to be more susceptible to dry conditions, especially in winter. Similarly, consistent temperatures throughout the year are indicative of climates like maritime, not continental. Thus, the presence of long winters and relatively short summers accurately encapsulates the essence of a continental climate.
