Any probe of the environment made to obtain information at various levels.

LIFTED INDEX- The environmental temperature at 500 millibars minus the 500 millibar parcel temperature on a Skew-T diagram. Negative LI values are unstable.

It is determined by lifting an air parcel to 500 millibars and then comparing its temperature to that of the environment. If the parcel is colder than its new environment, then the atmosphere is more stable.

They are obtained on a sounding by computing the area enclosed between the environmental temperature profile and the path of a rising air parcel, over the layer within which the latter is cooler than the former.

GEMPAKGeneral Environmental Meteorological Package (programming language) GENGeneral General CirculationThe totality of large-scale organized motion for the entire global atmosphere.

Transverse rolls are one type of transverse band, and often indicate an environment favorable for the subsequent development of supercells.

Environmental Protection Agency (EPA) and the National Oceanic and Atmospheric Administration (NOAA). Canadian hardness-gauge A type of disk hardness-gauge, especially useful in relatively soft snow. See disk hardness gauge.

The disadvantage to paper cones is that they are very sensitive to environmental conditions. Humidity particularly affects paper cones.

absolutely stable air An atmospheric condition that exists when the environmental lapse rate is less than the moist adiabatic lapse rate.

acclimation (acclimatization) Change that occurs in an organism to allow it to tolerate a new environment.

Quality and environmental management sytem From Meridional to Mountain and valley breeze MeridionalMeans that a flow goes from south to north or from north to south, collateral to the circles of longitude.

Under such conditions a parcel of air at the environmental temperature is unstable to upward vertical displacements if it is saturated, unstable to downward displacements if it is saturated and contains cloud water, ...

>> Hurricanes, or tropical cyclones, form in an environment of little or no vertical wind shear.

Dvorak Technique In 1975, Vern Dvorak, a meteorologist with the National Environmental Satellite Services, derived a method to analyze and predict tropical storm intensity based on real-time satellite imagery.

Observed values in thunderstorm environments often may exceed 1,000 joules per kilogram (j/kg), and in extreme cases may exceed 5,000 j/kg.

NATIONAL CENTERS FOR ENVIRONMENTAL PREDICTION (NCEP) As part of the National Weather Service, the centers provide timely, accurate, and continually improving worldwide forecast guidance products.

Stable: If rising air cools faster (DAR or MAR) than the surrounding air (Environmental Lapse Rate), then it will be cooler and denser than the surrounding air and will therefore tend to sink back down to its original elevation.

A large proportion of Australia's natural environment is farmed, harvested or managed by farmers. Many renewable resources, from topsoil to wildlife, are broadly under rural sector management.

For over a decade, I worked for the Ontario Ministry of Environment first as a meteorologist and later as head of air quality assessment. In the late 1970s I enjoyed doing some freelance writing on weather and weather history in my spare time.

GEOPHYSICS The study of the physics or nature of the Earth and its environment. It deals with the composition and physical phenomena of the earth and its liquid and gaseous envelopes.

High values indicate unstable and/or weakly-sheared environments; low values indicate weak instability and/or strong vertical shear.

GOES: Geostationary Operational Environmental Satellite GREENHOUSE EFFECT: The warming of the atmosphere by the trapping of longwave radiation being radiated to space. The gases most responsible for this effect are water vapor and carbon dioxide.

GOES: Geostationary Operational Environmental Satellite GROUND FOG: Fog produced over the land by the cooling of the lower atmosphere as it comes in contact with the ground. Also known as radiation fog, and in parts of California as tule fog.

Science that deals with the Earth's water bodies, their formation, circulation and distribution, their chemical and physical properties, and their interaction with the environment, including their relationship to living beings.

Deposition of acidic substances, resulting from long-range atmospheric transport of pollutants such as sulfur and nitrogen, which produce enhanced environmental acidification when they reach the Earth's surface.

CAPE is represented on a sounding by the area enclosed between the environmental temperature profile and the path of the rising air parcel, over the layer within which the latter is warmer than the former. This area is often called positive area.
