**The Earth's Diameter**
1. The earth's diameter is slightly larger at the equator than at the poles.
For the earth, this layer is considered to be roughly the lowest one or two kilometers of the atmosphere.

Lithosphere Earth's crust and that portion of the uppermost mantle directly below the crust, extending down to about 70 km (45 miles). Some use this term to refer to the entire Earth.
Hydrosphere- The Earth's water.
Hygrometer- An instrument that measures the water vapor content of the air.
Ice Crystals- Frozen water vapor suspended in the air.
Two points on the earth's surface, at opposite ends of a geomagnetic field line
Conservation Storage ...
Blowing sandSand particles picked up from the surface of the earth by the wind to moderate heights above the ground, reducing the reported horizontal visibility to less than seven statute miles.
Radiational CoolingThe cooling of the Earth's surface. At night, the Earth suffers a net heat loss to space due to terrestrial cooling. This is more pronounced when you have a clear sky.
Transport WindThe average wind over a specified period of time within a mixed layer near the surface of the earth.Transverse BandsBands of clouds oriented perpendicular to the flow in which they are embedded.
CLDCloud- A visible aggregate of minute water droplets or ice particles in the atmosphere above the Earth's surface.
Seisomograph An instrument used to measure and record earthquake vibrations and other earth tremors. Sensing element The element directly responsive to the value of the measured variable.
The four reservoirs, regions of the Earth in which carbon behaves in a systematic manner, are the atmosphere, terrestrial biosphere (usually includes fresh water systems), oceans, and sediments (includes fossil fuels).
large-scale circulation of winds around a central region of high atmospheric pressure, clockwise in the Northern Hemisphere, counterclockwise in the Southern HemisphereAnticyclonic RotationRotation in the opposite sense as the Earth's rotation, i.
There is a thin layer immediately above the earth's surface known as the surface boundary layer (or simply the surface layer).
coriolis forceA fictitious force used to account for the apparent deflection of a body in motion with respect to the earth, as seen by an observer on the earth.
Tides are the result of the gravitiational attraction of the sun and the moon on the earth. The attraction of the moon is far greater than the attraction of the sun due to the close proximity of the earth and the moon.
The Reseau Mondial Derived from French terms, "reseau mondial" translates literally to mean a "network of observations" for an Earth day.
The atmosphere is free and unrestrained by boundaries, only by the attraction that holds it to the earth and causes the density to decrease rapidly with height.
TORNADO - A region of rotation extending from the base of a thunderstorm or other convective cloud to the earth's surface. This is a vortex, or wind velocity field, with a speed of at least 40 MPH at the surface.

YEAR The interval required for the earth to complete one revolution around the sun. A sidereal year, which is the time it take for the earth to make one absolute revolution around the sun, is 365 days, 6 hours, 9 minutes, and 9.5 seconds.
Consider an area on the earth's surface. On the sides which face the wind, air will flow into the area, while on the other sides air will flow out.
Frost develops under conditions similar to dew, except the temperatures of the Earth's surface and earthbound objects fall below 32°F. As with the term "freeze", this condition is primarily significant during the growing season.
Processes by which traces gases or particles are transferred from the atmosphere to the surface of the earth.
Greenhouse Effect - The atmosphere allows solar radiation to reach the earth relatively easily.
The air flowing around a hurricane spins counter-clockwise in the northern hemisphere, and clockwise in the southern hemisphere (as does the earth, itself). In both hemispheres, this rotation is called cyclonic.
green house effect:process in which green house gases, like carbon dioxide in the Earth's atmosphere, cause thermal radiation emitted by the Earth's surface to be reflected back down, therefore causing the climate to warm.
greenhouse effect: a natural occurrence caused by certain greenhouse gases in the Earth's atmosphere.
Greenhouse Effect- the heating of the earth's atmosphere caused by imbalances in the atmosphere's radiation cycle, characterized by so called greenhouse gases such as water vapor and carbon dioxide, ...
Radiational Cooling - Cooling process of the Earth's surface and adjacent air, which occurs when infrared (heat) energy radiates from the surface of the Earth upward through the atmosphere into space.
Wind is the natural motion of the air moving parallel to the Earth's surface.
(or cyclonic rotation) Circulation (or rotation) which is in the same sense as the Earth's rotation, i.e., clockwise (in the Southern Hemisphere) as seen from above. Winds around synoptic-scale low pressure systems circulate cyclonically.
Geostationary satellite A satellite that orbits the Earth at the same rate and in the same direction as the Earth rotates so that the satellite is always directly over the same point (the sub-satellite point) on Earth's equator.
Gaseous envelope which surrounds the Earth.
Atmospheric Pressure
(pressure) Pressure (force per unit area) exerted by the atmosphere on any surface by virtue of its weight; ...
Troposphere: The portion of the earth's atmosphere from the surface to the tropopause; that is, the lowest 10-20 km of the atmosphere.
This happens at night, when heat absorbed by the Earth's surface during the day is radiated back into space. The highest degree of radiational cooling occurs on clear nights, when there are no clouds to reradiate the heat back to Earth.
The region around the earth in which the earth's magnetic field plays a dominant part in controlling the physical processes that take place.
Mammatus clouds
Clouds that look like pouches hanging from the underside of a cloud.
WIND - air in motion relative to the surface of the earth.
WIND ADVISORY - Sustained winds 25 to 39 mph and/or gusts to 57 mph. Issuance is normally site specific.

Thermosphere- The outermost layer of Earth's atmosphere.
Tornado- A rapidly whirling, funnel-shaped cloud that reaches down from a storm cloud to touch Earth's surface, usually leaves a destructive path.
Troposphere - 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, ...
Rain: Water vapor condensed in the atmosphere that falls to the earth in the form of drops (more than 0.5 mm [1/50 inch] in diameter). Depending on the average cycle of its accumulation in the rain gauge, it can be light (up to 2.5mm), moderate 2.
Biosphere - The totality of life forms on Earth.
Blackbody - A material that is able to absorb 100 percent of the radiation that strikes it.
Blizzard - A violent and extremely cold wind laden with dry snow picked up from the ground.
