For Troposphere we have terms and definitions in 12 topics. The topics are Air Quality, Atmospheric Chemistry, Climate, Climatology, Energy, Global Warming, Oceanography, Ozone Protection, Physical Geography, Satellite Meteorology, Science and Weather.

Troposphere (Air Quality)

The layer of the atmosphere nearest the earth's surface. The troposphere extends outward about 5 miles at the poles and 10 miles at the equator

Troposphere (Atmospheric Chemistry)

The lowest layer of the Earth's atmosphere, ranging from the ground to the base of the stratosphere with a altitude of 10-15 kilometers depending on the latitude. This is where all weather occurs. The word troposphere is derived from the Greek words tropos--turning and spharia--sphere.

Troposphere (Climate)

The inner layer of the atmosphere below about 15 km, within which there is normally a steady decrease of temperature with increasing altitude. Nearly all clouds form and weather conditions manifest themselves within this region, and its thermal structure is caused primarily by the heating of the Earth's surface by solar radiation, followed by heat transfer by turbulent mixing and convection.

Troposphere (Climatology)

The portion of the atmosphere which extends outward about 10 to 20 km from the earth's surface, and in which generally temperature decreases rapidly with altitude, clouds form, and convection is active

Troposphere (Energy)

The inner layer of the atmosphere below about 15 kilometers, within which there is normally a steady decrease of temperature with increasing altitude. Nearly all clouds form and weather conditions manifest themselves within this region. Its thermal structure is caused primarily by the heating of the earth’s surface by solar radiation, followed by heat transfer through turbulent mixing and convection.

Troposphere (Global Warming)

The inner layer of the atmosphere below about 15 kilometers, within which there is normally a steady decrease of temperature with increasing altitude. Nearly all clouds form and weather conditions manifest themselves within this region. Its thermal structure is caused primarily by the heating of the Earth's surface by solar radiation, followed by heat transfer through turbulent mixing and convection.

Troposphere (Oceanography)

The bottom layer of the atmosphere, closest to the surface of the Earth.

Troposphere (Ozone Protection)

The lower part of the earth's atmosphere, below 15 kilometers (9 miles). The troposphere is below the stratosphere.

Troposphere (Physical Geography)

Layer in the atmosphere found from the surface to a height of between 8 to 16 kilometers of altitude (average height 11 kilometers). The troposphere is thinnest at poles and gradually increases in thickness as one approaches the equator. This atmospheric layer contains about 80 % of the total mass of the atmosphere. It is also the layer where the majority of our planet's weather occurs. Maximum air temperature occurs near the Earth's surface in this layer. With increasing altitude air temperature drops uniformly with increasing height at an average rate of 6.5° Celsius per 1000 meters (commonly called the Environmental Lapse Rate), until an average temperature of -56.5° Celsius is reached at the top of the troposphere.

Troposphere (Satellite Meteorology)

The lowest of the four main layers of the atmosphere. Most weather occurs in the troposphere, the 10-20 km of the atmosphere envelope closest to the Earth.

Troposphere (Science)

The lowest portion of the atmosphere, in which the temperature drops with increasing elevation. Weather is largely confined to the troposphere.

Troposphere (Weather)

The layer of the atmosphere from the earth's surface up to the tropopause, characterized by decreasing temperature with height (except, perhaps, in thin layers - see inversion, cap), vertical wind motion, appreciable water vapor content, and sensible weather (clouds, rain, etc.).
