Unreferenced stub auto yes date December 2009 An atmospheric sounding is a measurement of vertical distribution of physical properties of the atmosphere atmospheric column such as atmospheric pressure pressure , temperature , wind speed and wind direction thus deriving wind shear , liquid water content, ozone concentration, pollution, and other properties. Such measurements are performed in a variety of ways including remote sensing and in situ Earth and atmosphericsciences in situ observations. The most common in situ sounding is a radiosonde , which usually is a weather balloon , but can also be a rocketsonde . Remote sensing soundings generally use passive infrared and microwave radiometer s airborne instruments surface stations Earth observing satellite instruments such as Atmospheric Infrared Sounder AIRS and Advanced Microwave Sounding Unit AMSU There is even a sounder at Mars the Mars climate sounder on the Mars Reconnaissance Orbiter Direct methods Sensors that measure atmospheric constituents directly such as thermometers, barometers and humidity sensors can be sent aloft on balloons, rockets or dropsonde s. They can also be carried on the outer hulls of ships and aircraft or even mounted on towers. In this case, all that is needed to capture the measurements are storage devices and or transponder s. Indirect methods The more challenging case involves sensors, primarily satellite mounted, such as radiometers , optical sensors, RADAR , LIDAR and similar light based instruments as well as sonar since these cannot measure the quantity of interest, such as temperature, pressure, humidity etc, directly.

About static atmospheric models weather prediction and climate models atmospheric model Static atmospheric models describe how the ideal gas properties namely pressure, temperature, density, and molecular weight of an atmosphere change, primarily as a function of altitude . For example, the US Standard Atmosphere is essentially a table of values for air temperature, pressure, and mass density, as a function of altitude above sea level. Other static atmospheric models may have other outputs, or depend on inputs besides altitude. Basic assumptions The gas which comprises an atmosphere is usually assumed to be an ideal gas , which is to say math rho frac M P R T math Where is mass density, M is average molecular weight, P is pressure, T is temperature, and R is the ideal gas constant. The gas is held in place by so called hydrostatic forces. That is to say, for a particular layer of gas at some altitude the downward towards the planet force of its weight, the downward force exerted by pressure in the layer above it, and the upward force exerted by pressure in the layer below, all sum to zero. Mathematically this is math P A P text d P A rho A text d h g 0 0 , math math text d P g 0 rho text d h , math Finally, these variables describing the system do not change with time i.e. it is a static system.

Unreferenced date December 2008 An atmospheric waveguide is an Earth s atmosphere atmospheric Fluid dynamics flow feature that improves the propagation of certain atmospheric wave s. The effect arises because wave parameters such as group velocity or vertical wavenumber depend on mean flow direction and strength. Thus, for instance, westerly wind westerlies might be a good waveguide for east ward traveling waves, but might strongly dissipation dissipate west ward traveling waves, by increasing or decreasing their vertical wavenumber, respectively. Modification of the waves group velocity will change their meridional propagation speed, directing them more geographical pole polewards or more equator wards. Category Atmosphere ... more details
An atmospheric wave is a periodic disturbance in the fields of atmospheric variables like surface pressure or geopotential height , temperature , or wind velocity which may either propagate traveling wave or not standing wave . Atmospheric waves range in Three dimensional space spatial and Time temporal scale from large scale planetary waves Rossby wave s to minute sound wave s. Atmospheric waves with periods which are harmonics of 1 solar day e.g. 24 hours, 12 hours, 8 hours... etc. are known as atmospheric tide s. Causes and effects The mechanism for the forcing of the wave, for example the generation of the initial or prolonged disturbance in the atmospheric variables, can vary. Generally, waves are either excited by heating or Dynamics mechanics dynamic effects, for example the obstruction of the flow by mountain ranges like the Rocky Mountains in the United States U.S. or the Alps in Europe . Heating effects can be small scale like the generation of gravity wave s by convection or large scale the formation of Rossby waves by the temperature contrasts between continents and oceans in the Northern hemisphere winter . Atmospheric waves transport momentum , which is fed back into the background flow as the wave dissipates . This wave forcing of the flow is particularly important in the stratosphere , where this momentum deposition by planetary scale Rossby waves gives rise to sudden stratospheric warming s and the deposition by gravity waves gives rise to the quasi biennial oscillation . In the mathematical description of atmospheric waves, spherical harmonics are used. When considering a section of a wave along a latitude circle, this is equivalent to a sinusoidal shape ... .
