Southeast doppler radar in motion12/16/2023 ![]() ![]() Attenuation Any process in which the intensity of radiation decreases due to scattering or absorption. Evidence suggests that the AMO has been active for at least the last 1,000 years. The SST difference between these warm and cool phases is about 0.5☌ and the period of the oscillation is roughly 20-40 years (the period is variable, but is a few decades long). Atlantic Multidecadal Oscillation (AMO) A natural oscillation of the North Atlantic SST between warm and cool phases. For example, El Niño is identified by sea surface temperature anomalies. Anomaly The deviation of a quantity over a specified period from the normal value for the same region. Aggregation The clumping together of ice crystals after they collide. The wave may reach maximum amplitude in the lower middle troposphere. African easterly wave A trough or cyclonic curvature maximum in the trade-wind easterlies. Absorption band A portion of the electromagnetic spectrum where radiation is absorbed and emitted by atmospheric gases such as water vapor, carbon dioxide, and ozone. Absorption The process by which incident radiant energy is retained by a material due to the material's physical composition. Absorber Anything that retains incident electromagnetic radiation due its physical composition. Rev., 132, 2094-2109.Ī Absolute angular momentum For the atmosphere, the absolute angular momentum, per unit mass of air, is the sum of the angular momentum relative to the earth and the angular momentum due to the rotation of the earth.
