Flow Mapping Applications Related to Severe Storm Development
-
Purpose: To construct an accurate rain-field by using quick and accessible lightning data.
-
Currently, satellite rainfall estimates are not retrieved instantaneously, but are delayed.
-
Lightning data can be gathered more quickly.
-
Motion vectors are generated by calculating the maximum correlation between each time interval within the lightning density data.
