Oceanic climate
A climate with mild winters, cool summers, and a small annual temperature range, shaped by the moderating influence of nearby oceans.
Maritime climate: A climate strongly moderated by the nearby sea, typically with smaller temperature ranges than inland climates. Oceanic climate is a regional expression of this broader maritime influence.
Köppen climate classification: A system that classifies climates using temperature, precipitation, and vegetation-related thresholds. It provides the widely used Cfb and related categories for oceanic climates.
Mediterranean climate: A climate with dry summers and mild, wetter winters, common around the Mediterranean Sea. Its pronounced summer dry season contrasts with the year-round precipitation typical of Cfb climates.
Growing season: The period each year when environmental conditions permit plant growth. Mild winters can lengthen growing seasons, although cool summers may slow heat-demanding crops.
Specific heat capacity: The heat required to raise the temperature of a unit mass of a substance by one degree. Water’s high heat capacity lets oceans absorb and release heat slowly, damping seasonal swings.
Cfb climate: A temperate climate with no dry season, warm rather than hot summers, and cool winters. This Köppen subtype represents the common temperate oceanic pattern.
Humid subtropical climate: A climate with hot, humid summers and mild winters, often with precipitation throughout the year. Its hotter summers distinguish it from the cooler summer profile of oceanic climates.
Cloud cover: The fraction of the sky obscured by clouds at a given place and time. Frequent cloudiness in many oceanic regions reduces sunshine and limits daytime warming.
Ocean current: A directed, persistent movement of seawater driven by winds, density differences, and other forces. Currents transport heat that can moderate nearby coastal temperatures.
Cfc climate: A cool oceanic climate with no dry season and fewer than four months averaging above 10°C. It describes the colder, often high-latitude or high-elevation edge of oceanic climates.
