The term “adiabatic” refers to a process where no heat is exchanged with the surrounding environment. When air sinks (subsides), the weight of the atmosphere above it increases, squeezing the air molecules together. This compression forces the molecules to move faster, which we detect as a rise in temperature. This is the opposite of adiabatic cooling, which happens when air rises and expands. Adiabatic heating is the reason why air descending the leeward side of a mountain range (like the Chinook or Foehn winds) becomes very warm and dry.

Primary pollutants are the direct result of combustion or industrial processes. Sulfur dioxide (SO2) is released when coal or oil containing sulfur is burned.

Primary pollutants are the direct result of combustion or industrial processes. Sulfur dioxide (SO2) is released when coal or oil containing sulfur is burned. Once in the atmosphere, SO2 can react with water vapor and oxygen to form sulfuric acid, which is a secondary pollutant and a major component of acid rain. Understanding the distinction is vital for environmental regulation, as controlling primary pollutants is the only way to prevent the formation of more toxic secondary substances. Other common primary pollutants include carbon monoxide and nitrogen oxides emitted from vehicle exhausts.

Chinooks occur when moist air from the Pacific is forced over the mountains. As the air rises, it loses its moisture as rain or snow on the western side. When this now-dry air spills over the crest and descends the eastern side, it is compressed by the higher pressure at lower elevations. This comprRead more
Chinooks occur when moist air from the Pacific is forced over the mountains. As the air rises, it loses its moisture as rain or snow on the western side. When this now-dry air spills over the crest and descends the eastern side, it is compressed by the higher pressure at lower elevations. This compression heats the air rapidly. Because the air is extremely dry and warm, it can sublimate snow directly into water vapor. Similar winds in the Alps are known as “Foehn” winds, demonstrating a universal atmospheric principle of mountain meteorology.

Pyranometers typically use a thermopile sensor under a glass dome. The sensor absorbs solar radiation, which generates a small electrical voltage proportional to the intensity of the light. This measurement includes both direct sunlight and "diffuse" sunlight reflected by clouds or the atmosphere. DRead more
Pyranometers typically use a thermopile sensor under a glass dome. The sensor absorbs solar radiation, which generates a small electrical voltage proportional to the intensity of the light. This measurement includes both direct sunlight and “diffuse” sunlight reflected by clouds or the atmosphere. Data from pyranometers is essential for calculating the Earth’s energy budget and for determining the efficiency of solar power plants. By monitoring variations in solar intensity, researchers can also track changes in atmospheric transparency caused by aerosols, pollution or volcanic ash.

Insolation is the primary driver of all weather and climate on Earth. Because the Earth is a sphere, the equator receives more direct, concentrated insolation than the poles, where the sun's rays hit at a shallow angle and are spread over a larger area. This unequal heating creates the pressure diffRead more
Insolation is the primary driver of all weather and climate on Earth. Because the Earth is a sphere, the equator receives more direct, concentrated insolation than the poles, where the sun’s rays hit at a shallow angle and are spread over a larger area. This unequal heating creates the pressure differences that drive global wind patterns. Furthermore, seasonal changes are entirely due to the tilt of the Earth’s axis, which changes the angle of insolation throughout the year. Understanding insolation patterns is the key to understanding why different regions have vastly different climates and ecosystems.
