31Yarkovsky effect — The Yarkovsky effect is a force acting on a rotating body in space caused by the anisotropic emission of thermal photons, which carry momentum. It is usually considered in relation to meteoroids or small asteroids (about 10 cm to 10 km in… …
32Global dimming — is the gradual reduction in the amount of global direct irradiance at the Earth s surface that was observed for several decades after the start of systematic measurements in 1950s. The effect varies by location, but worldwide it has been… …
33X-ray crystallography — can locate every atom in a zeolite, an aluminosilicate with many important applications, such as water purification. X ray crystallography is a method of determining the arrangement of atoms within a crystal, in which a beam of X rays strikes a… …
34Evapotranspiration — (ET) is a term used to describe the sum of evaporation and plant transpiration from the earth s land surface to atmosphere. Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and… …
35Aridity index — An aridity index (AI) is a numerical indicator of the degree of dryness of the climate at a given location. A number of aridity indices have been proposed (see below); these indicators serve to identify, locate or delimit regions that suffer from …
36hydrologic sciences — Introduction the fields of study concerned with the waters of the Earth. Included are the sciences of hydrology, oceanography, limnology, and glaciology. In its widest sense hydrology encompasses the study of the occurrence, the… …
37Radiative forcing — A change in average net radiation at the top of the troposphere (known as the tropopause) because of a change in either incoming solar or exiting infrared radiation. A positive radiative forcing tends on average to warm the earth s surface; a… …
38Wind turbine design — An example of a wind turbine, this 3 bladed turbine is the classic design of modern wind turbines Wind turbines History Design …
39Picea glauca — Mature white spruce in Alaska Conservation status …
40Microscale meteorology — is the study of short lived atmospheric phenomena smaller than mesoscale, about 1 km or less.[1] These two branches of meteorology are sometimes grouped together as mesoscale and microscale meteorology (MMM) and together study all phenomena… …
