- 1. ELEMENTS OF THE CLIMATE
- 2. INTRODUCCTION In this article I will talk about how it influences atmospheric pressure and wind climate. The factors of the atmospheric pressure are the average pressure, altitude and air temperature. And also I will discuss the factors of the wind.
- 3. ATMOSPHERIC PRESSURE The atmospheric pressure is the weight of a column of air on a place is measured with a barometer and is expressed as millibars (mb). The average pressure is measured at sea level. The areas with a pressure higher than the average are anticyclones (A) and the areas of lower pressure are depressions (B).
- 4. DIFFERENTS IN PRESSURE increase in altitude. -Air temperature: warm air is less, dense and lighter so its tends to rise. This produces low pressure and precipitations, cold air is denser and heavier, so its tends to fall. Its produces: high pressure or an anticyclone. ·Equator: permanent low pressure. ·Tropics and Poles: permanent high pressure. ·Temperate zones: high and low pressure alternates.
- 5. WIND Wind is the horizontal movement of air, it is measured with the anemometer and its direction is measured with the weather vane that is based on the cardinal point of the source of the wind. The factor that causes the wind is the difference in atmospheric pressure, the wind always blows from areas of high pressure towards areas of low pressure.
- 6. MOST IMPORTANT WINDS On the Earth, there are constant winds that transport hot air towards the cold zones and vice versa, maintaining equilibrium temperatures. The most important winds are: -Trade winds -West winds -Polar winds
