Tracking motions from satellite water vapor imagery: Quantitative applications to hurricane track forecasting. By James Franklin, Steve Nieman, Sim Aberson and Christopher Velden. Abstract. Water vapor imagery from GOES satellites has been available for over a decade. These data are used extensively, mainly in a qualitative mode, by. Infrared Water Vapor Channels are affected by cooling as the view angle increases. If the pixel location is farther from the sub-satellite point, the path the energy takes from Earth to satellite includes more of the colder upper atmosphere. For identical conditions, the brightness temperature might be 8 C cooler at the limb vs. at nadir. Interactively zoom and animate weather satellite images from a variety of geostationary satellites. Features of this site include: sectoring, animation of global images and at high resolution for a . Atmospheric motion vectors (AMV) are wind vectors derived by tracking the spatial 28 distributions of clouds and water vapor in consecutive satellite images.

Water vapor imagery is created using a wavelength sensitive to the moisture content in the atmosphere. 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. You can advance the imagery by placing your cursor over the image and using your mouse's. The fog product combines two different infrared channels to see fog and low clouds at night, which show up as dark areas on the imagery. WATER VAPOR IMAGERY: Water vapor satellite pictures indicate how much moisture is present in the upper atmosphere (approximately f ft to 30, ft). The highest humidities will be the whitest areas while dry regions will be dark. Operational Special Events Imagery (OSEI) Historical Page. Special Tropical Cyclone Pages.

Weather Analysis and Forecasting is a practical guide to using potential vorticity fields and water vapor imagery from satellites to elucidate complex weather patterns and train meteorologists to improve operational forecasting. In particular, it details the use of the close relationship between satellite imagery and the potential vorticity.
