amplitude"Often the greatest magnitude at a given point of any spatially and temporally varying physical quantity governed by a wave equation; can also mean the spatial part of a time-harmonic wave function.
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.
Amplitude
The maximum magnitude of a quantity. Often used to refer to the maximum height of a wave.
AMS ...
AM See amplitude modulation.
Analog Transmission of a continuously variable signal as opposed to a discretely variable signal. Compare with digital. A system of transmitting and receiving information in which one value (i.e.
The largest-amplitude atmospheric tides are mostly generated in the troposphere and stratosphere when the atmosphere is periodically heated as water vapour and ozone absorb solar radiation during the day.
Wave height or amplitude
The vertical distance between a wave crest and a trough.
Wave length ...
The wave may reach maximum amplitude in the lower middle troposphere or may be the reflection of an upper tropospheric cold low or an equatorward extension of a mid-latitude trough.
SHORT WAVE A progressive wave of smaller amplitude, wave length, and duration than a long wave.
Usually, it is in the form of a radio-frequency sine wave, modulated either in amplitude or in frequency. Carry-over The portion of the streamflow during any month or year derived from precipitation in previous months or years.
instability - A property of the steady state of a system such that certain disturbances or perturbations introduced into the steady state will increase in magnitude, the maximum perturbation amplitude always remaining larger than the initial ...
However, on both average (e.g. monthly) pressure maps and on individual days, long-wave trough/ridge patterns can be found - some having large amplitude, i.e.
While traveling in the deep oceans, tsunami have extremely long wavelengths, often exceeding 50 nm, with small amplitudes (a few tens of centimeters) and negligible wave steepness, ...
Attenuation - Any decrease in amplitude, density, or energy as result of an effect such as scattering, absorption, or friction. In physical meteorology, a reduction in radiation flow, especially solar radiation by atmospheric gases and aerosols.
This is a short amplitude trough embedded within the large scale flow. A baroclinic shortwave occurs when the isotherms cross the height contours at a sharp angle. Shortwaves are best defined on the 700 and 500 millibar charts.
Warm advection beneath an upper level ridge causes it to build (increase in amplitude), while cold advection beneath an upper level trough will contribute to its deepening.
A progressive wave of smaller amplitude, wave length, and duration than a long wave. It moves in the same direction as the basic current in which it is embedded and may induce upward vertical motion ahead of it.
Mid-latitude troughs have a north to south amplitude but in the tropics the opposite is the case. Inverted trough look like ridges but there is lower pressure at their centers of curvature.
Coherent Radar A radar that utilizes both signal phase and amplitude to determine target characteristics (e.g., velocity, spectrum width).
Cold Air Advection Transport of cold air into a region by horizontal winds.
LONG WAVE TROUGH A wave in the prevailing westerly flow aloft which is characterized by a large length and amplitude. A long wave moves slowly and is persistent. Its position and intensity govern weather patterns over a period of days or weeks.
Tropical Wave
A trough or cyclonic curvature maximum in the trade-wind easterlies. The wave may reach maximum amplitude in the lower middle troposphere.
Trough
(Thalwet) An elongated area of relatively low atmospheric pressure.
Meridional flow pattern Flow of westerlies in a series of deep troughs and sharp ridges; westerlies exhibit considerable amplitude.
Synchronous DetectionRadar processing that retains the received signal amplitude and phase but that removes the intermediate frequency carrier.
Rossby wavesA series of troughs and ridges on quasi-horizontal surfaces in the major belt of upper tropospheric westerlies. The waves are thousands of kilometers long and have significant latitudinal amplitude.
The waves are thousands of kilometers long and have significant latitudinal amplitude.RotationThe spinning of a body, such as the earth, about its axis.
