The Tropical Rainfall Measuring Mission (TRMM) 2A23 convective-stratiform separation algorithm applied to the TRMM satellite's Precipitation Radar (PR) identifies shallow, isolated precipitation over much of the tropical oceans. The shallow, isolated rain elements dominate the outer fringes of the tropical rain area but give way to deeper, more organized convective systems and associated stratiform areas toward heavy rain regions. The majority of the shallow, isolated radar echoes are

This reclassification leads to a more reasonable pattern of stratiform rain contribution across the tropics.
