Abstract
The present invention relates to a method of characterizing the convection intensity of a cloud by a meteorological radar.The reflectivity of said cloud to an electromagnetic wave being distributed in space, the distribution of the reflectivity being discretized according to a network of points (i, j, k) of the space in three dimensions, at least one profile (22) is defined as a normalized function of a parameter (21), which is in turn a given numeric function in two dimensions (i, j) of the distribution of the reflectivity at each point of the network, said normalized function varying uniformly between a minimum constant value and a maximum constant value, the function being equal to the minimum value when the parameter is less than a low threshold (threshold min) and being equal to the maximum value when the parameter is greater than a high threshold (threshold max), the cloud being characterized as convective when the profile is equal to one of the constant values and as stratiform when it is equal to the other constant value.The invention applies notably to meteorological radars on board aeroplanes.
