Water vapor satellite definition.

This web site should not be used to support operational observation forecasting emergency or. Notice the area of spin over seattle and the ripples over northern california and oregon. In this imagery bright blue and white areas indicate the presence of high water vapor or moisture content whereas dark orange and brown areas indicate little or no moisture present. Edt 1005 utc nasa s aqua satellite passed over tropical storm karina in the eastern pacific ocean and found highest concentrations of water vapor brown and coldest.

14 at 6 05 a m. The ineractive map makes it easy to navitgate around the globe. Water vapor imagery is used to analyze the presence and movement of water vapor moisture in the upper and middle levels of the atmosphere. The wavelength spectrum used to detect water vapor is in the 6 7 to 7 3 micrometer wavelength range.

Thus even though water vapor is an invisible gas at visible wavelengths our eyes can t see it and at longer infrared wavelengths the fact that it emits so readily between roughly 6 and 7 microns means the radiometer aboard the satellite can see it. Since water vapor is present everywhere water vapor satellite images show air motions in the atmosphere even in areas of blue skies with no clouds. Recognition and impact of vorticity maxima and minima in satellite imagery other resources to explore. Water vapor channel satellite imagery water vapor imagery analysis for severe weather water vapor imagery and pv.

Water vapor imagery is created using a wavelength sensitive to the moisture content in the atmosphere. The purple areas show more water vapor while red areas show less. The upper and middle levels of the atmosphere are from above the troposphere there is very little moisture. A satellite instrument tuned to such a wavelength can determine the temperature of these gases which emit the radiation.

Likewise the detection of extrasolar water vapor would indicate a similar distribution in other planetary systems. One such gas is water vapor.
