So, if we assume a certain drop size distribution (e.g., Marshall Palmer):
then recall: since Z = AR where A and b are empirically-derived constants. The most common form of this Z-R relation is for rain assuming a Marshal Palmer drop size distribution: Z = 200R |
Important Notes: - The aforementioned Z-R relation will vary from place to place and in different precip settings (e.g., convective versus stratiform)
- So, A and b will vary
- It also assumes a Marshall Palmer DSD.
