continental effect

Continentality is a meteorological concept measuring the difference between continental and marine climates. It's characterized by greater temperature fluctuations over land compared to water. This occurs because land has lower heat capacities and less evaporation than water surfaces, which distribute heat more effectively and use significant energy for evaporation, thus moderating temperature changes.1

The effect of continentality is also influenced by prevailing winds and ocean currents. In winter, continents can become cold air reservoirs, while oceans retain heat. This temperature contrast can lead to storm development on continental eastern sides and oceanic western fringes. Conversely, in summer, continents heat up faster, creating low-pressure areas that draw in moist air, resulting in monsoons.2

Marine west coast climates, found poleward of Mediterranean climates, experience more moderate temperatures and consistent precipitation due to oceanic influence. In contrast, continental subarctic climates, located further inland, are dominated by long, extremely cold winters and short, mild summers, with significant annual temperature ranges.34
