Stratiform and Convective Rain Discrimination Deduced From Local $P(R)$

Application of the SC EXCELL model for rain attenuation prediction in tropical and equatorial regions

“…( ) = ( ) + ( ) (4) To this aim, the procedure described in [10] (recalled in [3] as well) is employed in order to discriminate between stratiform and convective rainfall statistics.…”

“…Without going into the details of the whole procedure (for which the reader is addressed to [10]), the algorithm classifies as mainly stratiform (convective) those synthetic rain cells for which the peak rain rate R M < R M,th (R M ≥ R M,th ). R M,th is the peak discrimination threshold that is calculated on the basis of the local yearly P(R) and by setting 10 mm/h as a reasonable rain rate stratiform/convective discrimination threshold [4], [5].…”

“…The performance of rain discrimination method has been compared against time series of rain intensity collected by a disdrometer. More details about the rain discrimination results reported in figure 3 can be found in [10]. …”

“…Monthly distribution of stratiform and convective rainfall events occurred in Kuala Lumpur for a period of 3 years[10].…”

Modified rain attenuation prediction method considering the effect of wind direction

“…Rainfall is usually classified as lighter stratiform rain and consisting of smaller drops, or as convective rain, heavier and more localized. Spatial weather radar maps of reflectivity, which is a measure of rainfall intensity, show small areas of higher rain rate imbedded in larger regions of lighter rain and can be used to separate areas of convective and stratiform precipitation [10], [11]. Tropical rainfall is usually considered convective in nature, but almost all convection occurs in association with stratiform rain [12].…”
