A boundary between the saturated zone and the atmosphere along which groundwater discharges at practically atmospheric pressure.
Industry:Weather
A bolometer that has some capability to resolve the electromagnetic spectrum.
Industry:Weather
A body that reflects radiance isotropically. See Lambert's cosine law.
Industry:Weather
A biologic or geologic structure of known age from which information on past climate may be extracted; may also be used with reference to climate information extracted from historical documents. Proxy climate records are of use for times and places lacking instrumental records. Examples include fossil species assemblages from rocks, geomorphic structures, the isotopic or species composition of marine or lacustrine sediments, the isotopic and other chemical composition of polar and very high elevation ice, and the structure and chemical composition of annual growth rings in trees and growth bands in corals.
Industry:Weather
A body of subsurface water flowing through interconnected caves or caverns or through large interconnected interstices.
Industry:Weather
A body that emits radiance isotropically. See Lambert's cosine law.
Industry:Weather
A body of (often temporarily) stored water, generally of moderate dimensions, supported by a relatively impermeable stratum, and located between a water table and the ground surface.
Industry:Weather
A belt of trees and/or shrubs arranged as a protection against strong winds; a type of windbreak. The trees may be specially planted or left standing when the original forest is cut. A shelterbelt decreases the force of the wind near the ground, both upwind for a distance of up to six times the height of the barrier, and downwind for a distance of fifteen to twenty times the height. These ratios are roughly constant, irrespective of the height of the belt. The lowest wind speed is found downwind at a distance of three or four times the height of the belt. If the trees are too dense, the air beyond this quiet zone is often turbulent, with downdrafts that may flatten crops. The best form is a moderately dense belt of mixed conifers and deciduous trees, five to ten yards wide, containing at least three rows of trees at right angles to the prevailing winds. A system of shelterbelts to give protection to crops over a large area should be planted at intervals of about twenty-five times their expected height.
Industry:Weather
A band of relatively strong winds concentrated between 20° and 40° latitude in the middle and upper troposphere. It can be present at any longitude but is generally strongest off the Asian coast. See jet stream.
Industry:Weather
A band of low pressure located, in the mean, between 50° and 70° latitude. In the Northern Hemisphere, this belt consists of the Aleutian low and the Icelandic low. In the Southern Hemisphere, it is supposed to exist around the periphery of the Antarctic continent.
