Abstract

A user-selectable cursor can be positioned over a portion of a cloud formation displayed on a computer display, where the portion corresponds to precipitation that is expected to move over a target point or area. Predicted precipitation amounts corresponding to the portion are calculated and displayed, allowing the user to see how much precipitation is expected to occur over the target point or area. In one variation, radar reflectivity data indicating relative storm intensities is displayed on the computer screen, and the cursor is used to select a region of interest including one or more cells that are expected to move over a target area. Reflectivity values for each cell that is expected to move over the target area are converted into predicted precipitation rates, and are multiplied by the time that each cell is expected to remain over the target area. Predicted precipitation amounts attributable to each cell that is expected to move across the target area are accumulated and output as a predicted precipitation amount for the target area. If the target area is a watershed comprising multiple cells, then predicted precipitation amounts for each cell in the watershed are averaged to produce a predicted precipitation amount for the watershed. The cursor can be drawn over different regions of interest to allow a user to quickly identify outcomes under different scenarios.
