The Normal Lapse Rate is the average rate at which air temperature decreases with increasing altitude in the troposphere. The standard value is approximately 6.5°C for every 1,000 meters (or 3.6°F per 1,000 feet). This rate is used by scientists ...
The Aurora Borealis (Northern Lights) occurs when charged particles from the sun—the solar wind—interact with the Earth’s magnetic field. These particles are funneled toward the poles, where they collide with oxygen and nitrogen atoms in the ionosphere. These collisions release ...
A ceilometer is a specialized meteorological instrument used to determine the height of a cloud base or the “ceiling.” It uses a laser or other light source to measure the time it takes for a pulse to reflect off the ...
Cumulonimbus clouds are towering, dense clouds associated with thunderstorms and unstable atmospheric conditions. Known as “thunderheads,” they can span the entire height of the troposphere, often developing a flat, anvil-shaped top where they hit the tropopause. They are the primary ...
