The science of the formation of riverbeds, flood plains, and stream forms by the action of water.
Industry:Weather
The sector, in a horizontal plane, between the occluded front and a secondary cold-front of an occluded cyclone.
Industry:Weather
The representation of physical or mathematical data by the use of the Fourier series or Fourier integral.
Industry:Weather
The rise in stage, culminating in a crest and followed by recession to lower stages, associated with a flood.
Industry:Weather
The risk of damage by frost. It may be expressed as the probability or frequency of killing frost on different dates during the growing season, or as the distribution of dates of the last killing frost of spring or the first of autumn. A strict application of the concept would take into account the actual species or group of plants that might potentially be killed, as different plants sustain frost damage at different temperatures. Wind-chill factors should also be considered.
Industry:Weather
The ratio of the Reynolds stress at the surface to the square of the geostrophic wind velocity.
Industry:Weather
The ratio of transmitted irradiance to the incident irradiance. Used to distinguish from the transmittance of radiance in a specific direction only.
Industry:Weather
The relationship between topography and winds. There are two main mechanisms: 1) topographically modified flow, where existing synoptic- scale winds are modulated or redirected by the presence of mountains or terrain features; and 2) geographically generated flow, where solar heating and nocturnal cooling generate anabatic and katabatic flows and mountain and valley circulations during conditions of weak synoptic winds.
Industry:Weather
The rapid variations of the electric field at the earth's surface and beneath, within, and above thunderclouds. Used to determine quantitative estimates of the charge transferred during a lightning discharge, heights of the charge centers (regions or volumes of net charge in the atmosphere), and many other features of thunderclouds.
