Abstract: Described are a method and a system for generating a weather radar display. The method includes determining proxy meteorological radar data for a first area of a geographical region for which meteorological radar data are unavailable. The proxy data are determined from a plurality of alternative meteorological data streams each having data representative of a value of a different meteorological parameter that is not observable by radar. The method further includes determining graphical meteorological radar data for the geographical region based on the proxy meteorological radar data for the first area in the geographical region and meteorological radar data for a second area in the geographical region. Examples of graphical meteorological radar data that are generated include vertically integrated liquid, composite reflectivity and echo tops data.

Abstract: Described are a method and an apparatus for generating a forecast weather image such as a forecast weather radar image. The method uses filters to approximate viscous alignment and to thereby determine displacement fields having meaningful structure. In various embodiments a power-law energy spectrum is utilized for deformations in the displacement field through the application of a set of Gabor filters. The Gabor filters are applied in a sequential manner to gradient error images and values of modes of motions corresponding to the Gabor filters are determined. The values are used to generate the displacement field which can then be applied to an existing weather image to generate a forecast weather image.

Abstract: Described are a method and a system for generating a short-term forecast of echo tops as defined by weather radar measurements. The method includes receiving echo tops images for different times. An echo tops growth rate and an echo tops maximum value are determined for pixels in one of the images and used to generate echo tops prediction values for an echo tops prediction image. For pixels in regions of the image determined to be subject to convective initiation but where convective weather does not exist, an echo tops initiation height and the echo tops maximum value are determined and used with a predicted precipitation value to generate an echo tops prediction value for each pixel.
