Climatic characteristics of oceanic climates, temperate oceanic climate characteristics

Oceanic climate is the most basic type of climate on Earth. The general feature is that it is less influenced by the continent and more affected by the ocean. Under the conditions of oceanic climate, the annual and diurnal variations of temperature are relatively gentle, and the annual and diurnal ranges are smaller than those of continental climates.

Spring temperatures are lower than autumn temperatures. The annual maximum and minimum temperatures occur later than those of continental climates. The hottest month is in August and the coldest month is in February.

The climate is formed by the action of the huge water bodies of the ocean. This includes the climate of the ocean surface or islands and the offshore part of the continent where air currents prevail from the ocean. The marine climate has the following characteristics:

The annual and diurnal variations in temperature are very small, and diurnal variations are not even observed on the ocean surface. The extreme value of the annual variation is generally delayed by one month compared with the mainland, such as February for the coldest month and August for the warmest month. The coldest month in the high latitudes is likely to be March, and the warmest month is likely to be September.

Autumn is warmer than spring.

The seasonal distribution of precipitation is relatively even, and the number of precipitation days is large, but the intensity is small. The frequency of clouds and fog is high and the humidity is high.

Storms in tropical oceans, such as the southwestern part of the North Pacific and the South China Sea, are areas where typhoons generate and affect strongly. Tropical storms, including typhoons, are a very important meteorological hazard.

Cloudy and foggy weather with high humidity. Most continental areas close to the ocean have oceanic climate characteristics, and the coastal areas of Western Europe are typical oceanic climate zones on the continent.

The oceanic climate is characterized by little influence by the continent and large influence by the ocean, the annual and daily variation of temperature is relatively moderate, the spring temperature is lower than the autumn temperature, the hottest month is in August, the coldest is in February, the coldest in the high latitudes may be March, the warmest month may be August, and the seasonal distribution of precipitation is relatively even.

Temperate oceanic climate refers to a type of oceanic climate, which is characterized by mild seasons, abundant precipitation, low summer temperatures, and winter temperatures. The temperate oceanic climate is characterized by the following:1

Low annual average temperature: The average annual temperature in temperate oceanic climates is generally above 10, with a maximum of 20 and a minimum of 0. 2.

Temperate seasons: The temperature difference between the four seasons in temperate oceanic climate is small, the temperature in summer is not high, the temperature in winter is not low, and the temperature in spring, summer, autumn and winter is mild in all seasons. 3.

Abundant precipitation: Precipitation is abundant in temperate oceanic climates, mostly heavy rainfall. 4.

High humidity: The humidity of temperate oceanic climate is large, generally above 70%, and there are many haze weather. 5.

Low air pressure: Temperate oceanic climates have low air pressure, generally below 1010 MB, and the center of the low pressure zone is located here.

The temperate oceanic climate is characterized by the following: drynessThe average temperature of the coldest month is above 0 degrees Celsius, and the average temperature of the hottest month is below 25 degrees Celsius, and the annual temperature difference is small.

It is humid and rainy throughout the year, especially in winter. There is no dry season throughout the year, with more cloudy days and fewer sunny days.

Temperate marine climate is a type of climate that is mild and humid throughout the year, and its characteristics are very obvious: there is no severe cold in winter, no heat in summer, and precipitation is evenly distributed throughout the year.

It is found on the west coast of the continent between latitudes and 40-60°.

Including Western Europe, the northwest of the United States, the southwest of Canada, Chile and New Zealand, Western Europe is the most typical, so it is also called Western European climate. Under the influence of the westerly wind belt and the warm current of the ocean, it is not hot in summer, and cold in winter, with more precipitation and even distribution of seasons, giving people a comfortable living environment.

Temperate oceanic climateFeatures: warm in winter and cool in summer, small annual temperature difference.

The closer you are to the ocean, the more oceanic the climate is. Especially in winter, because there is a warm current along the coast, the westerly wind blows late from the warm current and the sea, and the air flow is warm and humid, so the winter temperature is much warmer than that of the center of the continent and the east coast of the continent at the same latitude.

Due to the warm winters and cool summers, the annual temperature difference is much smaller than in other regions at the same latitude. Rain throughout the year, more rain in winter: This area is on the path of extratropical cyclone activity, and cyclone rainfall is abundant, especially in winter, when extratropical cyclones are more active, with many rainy days, but the intensity of precipitation is not large.

Laws of distribution

Located on the west coast of the continent at 40 60 degrees north and south latitudes, except for Asia and Antarctica, there are all other continents, among which the western part of the European continent and the British Isles (European continent) are the most typical. Temperate oceanic climates tend to be found only on narrow strips or islands.

The temperate oceanic climate is most typical in Western Europe, and its distribution area is the most large, and it is also distributed in the corresponding latitudes on the west coast of the American continent, as well as in Tasmania and New Zealand in Oceania. This climate is found in northwestern Europe, the Pacific coast of Canada, southern Chile and a small southeastern part of Australia.

Western Europe is located at about 30 40° north latitude and is affected by westerly winds, which can be affected by water vapor blowing from the Atlantic Ocean. The terrain of North America is high in the west, bottom in the middle, and slightly higher in the east, and the water vapor blowing from the Pacific Ocean is blocked by the Rocky Mountains, which can only be affected by the coastal margins, and the warm Alaskan current passes through.
