October 23, 2002: Moderate Stratiform Precipitation Author: Pam Heinselman, CIMMS/OU Last Updated: 3 April 2003

Forecast/Weather:

Stratiform precipitation moves across central Oklahoma and dissipates during period on CD.

Radar Operations:

Start time: 13:26 10/23/02 UTC (13:26 10/23/02 local time)
Stop time: 23:50 10/23/02 UTC (23:50 10/23/02 local time)
Data on CD between 13:26 and 20:44 is ~hourly.

Radar/Operational Status:

Hydrometeor Classification Algorithm: Warm season

Operational Delivery:

Not applicable.

Snapshots:

Figure 1: Radar reflectivity displays stratiform precipitation over central Oklahoma at 16:18 UTC on 10/23/02.	Figure 2: A ring of smaller correlation coefficients (i.e., 0.93) in the northern part of the system suggests the presence of hail within a melting layer.
Figure 3: Larger (smaller) values of specific differential phase in the northern (southern) part of the system indicates heavier (lighter) precipitation. Also, pockets of zero KDP, colocated with pockets of low RhoHV, offers further evidence of hail within a melting layer.	Figure 4: The hydrometeor classification algorithm classifies mostly moderate precipitation within the northern part of the system and light precipitation within the southern part of the system.
