Structure of the atmosphere

Atmospheric layers are characterized by variations in temperature resulting primarily from the absorption of solar radiation; visible light at the surface, near ultraviolet radiation in the middle atmosphere, and far ultraviolet radiation in the upper atmosphere.

Troposphere

• The troposphere is the atmospheric layer closest to the planet and contains the largest percentage (around 80%) of the mass of the total atmosphere.
• Temperature and water vapor content in the troposphere decrease rapidly with altitude.
• Water vapor plays a major role in regulating air temperature because it absorbs solar energy and thermal radiation from the planet’s surface.
• The troposphere contains 99 % of the water vapor in the atmosphere.
• Water vapor concentrations vary with latitude. They are greatest above the tropics, where they may be as high as 3 %, and decrease toward the polar regions.
• All weather phenomena occur within the troposphere, although turbulence may extend into the lower portion of the stratosphere.
• Troposphere means “region of mixing” and is so named because of vigorous convective air currents within the layer.
• The upper boundary of the layer, known as the tropopause, ranges in height from 5 miles (8 km) near the poles up to 11 miles (18 km) above the equator. Its height also varies with the seasons; highest in the summer and lowest in the winter.
