Abstract
Described are a method and a system for detecting an atmospheric feature. A value of a meteorological scalar field at an initial time is determined for a set of tracers. Each tracer is initialized at a first tracer location. An integration time is selected according to a coherence time of a type of the feature to be detected. Alternatively, or in combination with the selected integration time, a spatial resolution of the wind field is selected according to a spatial scale of the type of feature to be detected. Each tracer is advected to a second tracer location at an earlier time according to the integration time and the wind field. A value of the meteorological scalar field at the earlier time and second tracer location is determined for each tracer and summed with the value at the first location to generate an integrated value of the meteorological scalar field.
