Pacific Ocean is the largest water reservoir in the world.It stretches from the north of the planet to its south, reaching the coast of Antarctica.The greatest width reaches the equator, in tropical and subtropical areas.Because the climate of the Pacific is defined as more than a warm, because most of it falls in the tropics.In this ocean there are both warm and cold currents.It depends on to what the continent in a particular place and which adjoins the Gulf of him formed atmospheric flows.
Atmospheric circulation
largely depends on the climate of the Pacific Ocean from atmospheric pressure, which is formed on it.In this section, geographers are five main areas.Among them there are zones and high and low pressure.In the subtropics in both hemispheres of the planet over the ocean formed by two areas of high pressure.They are called the North Pacific or Hawaiian maximum and the South Pacific high.The closer to the equator, the pressure becomes lower.Also note that in the Western Hemisphere atmospheric dynamics are lower than in the east.In the north and the south ocean formed dynamic lows - Aleut and Antarctic respectively.North exists only in the winter season, and the south by its atmospheric characteristics stable throughout the year.
Wind
such factors as the trade winds, largely affects the climate of the Pacific Ocean.Briefly, these wind currents are formed in the tropics and subtropics in both hemispheres.There has for centuries established a system of trade winds, which cause warm currents and stable hot air temperature.They are separated by a strip of the equatorial lulls.This area is dominated by calm, but sometimes there are small light wind.In the north-western part of the ocean are the most frequent visitors of the monsoons.In winter, the wind blows from the Asian continent, bringing cold and dry air.Summer ocean breeze blowing, thereby increasing the humidity and air temperature.Temperate climate zone, as well as the entire southern hemisphere, starting with a subtropical climate, is subject to strong winds.The climate of the Pacific Ocean in these areas is characterized by typhoons, hurricanes, gusty winds.
Temperature
order to clearly understand what the temperature is characterized by the Pacific Ocean, the card will come to help us.We see that this body of water located in all climatic zones, starting from the north, ice, passing through the equator and ending south, and ice.Above the surface of the entire body of water is subject to climate latitudinal zonation and winds that bring in certain regions of hot or cold temperature.In equatorial latitudes thermometer shows 20 to 28 degrees in August, roughly the same performance observed in February.In temperate latitudes February temperatures reach -25 Celsius, while in August the thermometer rises to 20.
flow characteristics and their influence on the temperature
The climate of the Pacific lies in the fact that in some latitudes at one and the same time, there may be a different weather.So things are going, because the ocean is made up of various currents that bring here from the continents warm or cold cyclones.So, first consider the Northern Hemisphere.In the band of the tropics western part of the reservoir is always warmer than the east.This is due to the fact that in the west of the water warmed by trade winds and currents of the Kuroshio and East Australian.In the east, the water cooled by the Peruvian and the California Current.In the band of temperate climate, on the contrary, warmer east west.Here the western part of the Kuril over cooled and heated through eastern Alaska.If we consider the southern hemisphere, the essential difference between East and West was not found.It all happens naturally, because the trade winds and winds at high latitudes are distributed over the surface of the water temperature the same.
Clouds and pressure
Pacific climate also depends on atmospheric phenomena, which are formed on one or another of his area.Raising the air flow is observed in areas of low pressure, as well as in coastal areas, where there is a mountainous terrain.The closer to the equator, the less water going over the clouds.In temperate latitudes, they are in the 80-70 percent in the subtropics - 60-70%, in the tropics - 40-50%, while at the equator only 10 percent.
Precipitation
Now consider what the weather is fraught with the Pacific Ocean.Map climatic zones it shows that the highest humidity here falls on tropical and subtropical zones, which are located north of the equator.Here rainfall is equal to 3000 mm.In temperate latitudes, this figure is reduced to 1000-2000 mm.Also note that in the West the climate is always drier than the East.The most arid regions of the ocean is considered a coastal area near the California peninsula and the coast of Peru.Here, due to problems with condensation precipitation is reduced to 300-200 mm.In some areas, it is very low and amounts to only a 30-mm.
Climate Seas Pacific
In the classic version made to believe that the water tank has three seas - Japan, Bering and Okhotsk.These reservoirs are separated from the main tank islands or peninsulas, they are adjacent to continents and countries belong, in this case Russia.Their climate is determined by the interaction of the ocean and the land.The average temperature on the surface of the water in February is approximately 15-20 below zero in the coastal zone - 4 below zero.The Sea of Japan is the warmest, because it keeps the temperature within five degrees.The most severe winters are in the north of the Sea of Okhotsk.Here the thermometer can show below -30 degrees.Summer sea average heated to 16-20 above zero.Naturally, in this case Okhotsk is cold - + 13-16, and Japan may reach 30 or more.
Conclusion
Pacific Ocean, which is, in fact, the largest geographical feature of the planet, has a very diverse climate.Regardless of the time of year above its waters formed a specific atmospheric effect that generates low or high temperatures, strong winds or calm.
