A radar system is configured to predict future storm cell characteristics and display an indication of the characteristics on an electronic display. The system has an antenna configured to receive radar returns from radar scans of storm cells. The system includes processing electronics configured to determine a characteristic of a first storm cell from the radar returns and identify at least one second storm cell. The at least one second storm cell is in the same weather system as the first storm cell. The processing electronics are configured to determine the characteristic for the at least one identified second storm cell, compare the characteristic of the first storm cell with the characteristics of the at least one second storm cell, determine a growth rate of the first storm cell, and calculate a predicted height of the first storm cell at a future time based on the comparison and determined growth rate.

Storm top detection and prediction

A method of predicting storm cell characteristics at a future time is provided. A value relating to a characteristic of the storm cell is determined from reflectivity data processed from signals received from a radar scan of the storm cell. A second storm cell is identified that is part of the same weather system as the storm cell. A plurality of values relating to the characteristic for the identified second storm cell is received from a memory wherein the plurality of values were determined at a plurality of different times. The determined value of the storm cell is compared with the determined plurality of values of the identified second storm cell. A growth rate of the storm cell is determined. A maximum height of the storm cell at a third time in the future is calculated based on the comparison and the determined growth rate and presented to a user.

The present invention is directed to a system and method for a safe flight display through increasing situation awareness by an optimal presentation, given limited capacity of the system. The system may determine which terrain area needs a detail representation and which area needs a coarse representation. A view-dependent visual error metric may be utilized to define and maintain an error bound and accurately minimize the amount of terrain data being depicted. By performing a breadth-first search on the terrain database, a user can determine amount of geometry to be displayed with limited bandwidth of data presentation. The user may be allowed to scale the application to his/her desired level of detail, given a capacity of the system. Therefore, the system may provide a safe flight display with an anticipated and graceful (all portions of the screen would be given an equal quality representation) degradation in performance upon the choice of the user.
