1. A method of displaying a weather condition indicator with respect to an aircraft, the method comprising:
- receiving weather data from a weather radar system, the weather data including data indicative of a first location of the weather condition;
determining a second location of the weather condition based on data indicative of a movement of the weather condition with respect to the first location;
displaying the weather condition indicator with reference to the second location; and
adjusting a size of the weather condition indicator based on at least one of an error estimate and a change estimate.

Abstract
A method of displaying a weather condition indicator with respect to an aircraft includes receiving weather data from a weather radar system. The weather data includes data indicative of a first location of the weather condition. The method also includes determining a second location of the weather condition based on data indicative of a movement of the weather condition, and displaying the weather condition indicator with reference to the second location.

4. A method of displaying a weather condition indicator with respect to an aircraft, the method comprising:
-
receiving weather data from a weather radar system, the weather data including data indicative of a first location of the weather condition; determining a second location of the weather condition based on data indicative of a movement of the weather condition with respect to the first location; and displaying the weather condition indicator with reference to the second location, wherein the data indicative of the movement of the weather condition includes a motion vector, and wherein determining the second location includes determining a distance with respect to the first location using the motion vector. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)

12. An aircraft weather radar system, comprising:
-
a processor; and a non-transitory memory coupled to the processor and containing program instructions that, when executed, cause the processor to; receive weather data from first and second ground-based weather radar systems having separate locations, the weather data including data indicative of a first location of a weather condition; determine a second location of the weather condition based on data indicative of a movement of the weather condition with respect to the first location; and generate an indicator of the weather condition with reference to the second location. - View Dependent Claims (13, 14, 15, 16, 17)

18. A weather radar system, comprising:
-
a processor; and a non-transitory memory coupled to the processor and containing program instructions that, when executed, cause the processor to; receive weather data including location and motion vector data for weather cells in a region of interest; generate a grid pattern having grid points for the region of interest; assign respective motion vector data received for each of the weather cells to one or more of the grid points near the location of the weather cell in the region of interest to generate a first set of assigned grid points; assign linearly interpolated motion vector data to unassigned grid points between the grid points in the first set of assigned grid points to generate a second set of assigned grid points; determine estimated motion vector data for unassigned grid points outside of the first set of assigned grid points to generate a third set of assigned grid points; determine an updated location for each of the grid points using the motion vector data assigned to the first, second, and third sets of assigned grid points; and generate an indicator of a weather condition associated with the weather cells with reference to the updated locations. - View Dependent Claims (19, 20)
