The maximum partial pressure (saturation pressure) of water vapor in air varies with temperature of the air and water vapor mixture.
The maximum amount of water vapor necessary to keep moist air in equilibrium with a surface of pure water or ice. It represents the maximum amount of water vapor that the air can hold at any given temperature and pressure.
Radius of Maximum Winds: The distance from the center of a tropical cyclone to the location of the cyclone's maximum winds. In well-developed hurricanes, the radius of maximum winds is generally found at the inner edge of the eyewall.

BRIGHT BAND- A maximum in the radar reflectivity caused by snow melting as it falls. Melting snow can have a reflectivity similar to small hail.
A local wind speed maximum within a jetstream.
Jetstream
Relatively strong winds concentrated in a narrow stream in the atmosphere, normally referring to horizontal, high-altitude winds.
Flood Crest - Maximum height of a flood wave as it passes a certain location.
Flood Stage - The level at which a stream, river or other body of water begins to or will begin to leave its banks.
Amplitude: The maximum magnitude of a quantity.
Anabranch: A diverging branch of a river which re-enters the main stream.
Analog: Class of devices in which the output varies continuously as a function of the input.
Flood Crest The Maximum height of a flood wave as it passes a location.
Visibility: The maximum horizontal distance at which objects can be identified.
Visible radiation: Electromagnetic radiation with wavelengths between approximately .4 to .7 microns. Human vision occurs at these wavelengths.
When do maximum and minimum temperatures occur?
A. A common misconception, is that it must be coldest in the middle of the night, and warmest around midday. On some occasions, mainly due to air mass changes, this may be correct, but not usually.
SATURATION POINT The point when the water vapor in the atmosphere is at its maximum level for the existing temperature. SCATTERED The amount of sky cover for a cloud layer between 3/8ths and 4/8ths, based on the summation layer amount for that layer.
These bursts are associated with some major flare events beginning 10 to 20 minutes after the flare maximum, ...
Tropical DepressionA tropical cyclone in which the maximum 1-minute sustained surface wind is 33 knots (38 mph) or less.
This surface usually is located slightly below the lowest point of the stream bottom such that the gage height is usually slightly greater than the maximum depth of water.
Saturation The condition of the atmosphere when the amount of water vapor present is the maximum possible at the existing temperature.
Daily Flood PeakIn hydrologic terms, the maximum mean daily discharge occuring in a stream during a given flood event.DALRDry Adiabatic Lapse RateDamIn hydrologic terms, any artificial barrier which impounds or diverts water.
Entrance Region - The region upstream from a wind speed maximum in a jet stream (jet max), in which air is approaching (entering) the region of maximum winds, and therefore is accelerating.
It has been observed in some places that the January wind is relatively constant through the 24 hours of the day, while the July wind is perhaps half as large during the night, but increases to a noon maximum near the January level.
Retreater With the conversion to electronic maximum/minimum thermometers by most governmental weather services, this term is hardly used anymore.
Within the eye wall, the wind speed reaches its maximum but within the eye, the winds become very light sometimes even calm.
The region upstream from a wind speed maximum in a jet stream (jet max), in which air is approaching (entering) the region of maximum winds, and therefore is accelerating.
CAPE is directly related to the maximum potential vertical speed within an updraft; thus, higher values indicate greater potential for severe weather.
The index is computed by subtracting a base temperature of 50oF from the average of the maximum and minimum temperatures for the day. Minimum temperatures less than 50oF are set to 50, and maximum temperatures greater than 86oF are set to 86.
RUNWAY VISUAL RANGE (RVR) It is the maximum distance at which the runway, or the specified lights or markers delineating it, can be seen from a position above a specified point on its center line.
A relative pressure maximum. An area of pressure that has diverging winds and a rotation opposite to the earth's rotation. This is clockwise the Northern Hemisphere and counter-clockwise in the Southern Hemisphere.
Saturation vapor pressure The maximum amount of water vapor necessary to keep moist air in equilibrium with a surface of pure water or ice.

Saturation mixing ratio Maximum concentration of water vapor in a given volume of air at a specific temperature.
Saturation vapor pressure The maximum vapor pressure in a sample of air at a specific temperature.
Mixing depth - the maximum height air pollution normally reaches. This varies with geography, season and time of day.
Monsoon - A wind caused by differences in surface temperatures. Some produce heavy rains.
JET STREAK- A relative maximum of windflow within the jet stream.
JET STREAM - Strong winds concentrated within a narrow band in the atmosphere. The jet stream often "steers" surface features such as fronts and low pressure systems.
