October 29, 2002: End of 28 Oct '02 Event and AP/BS Author: Pam Heinselman, CIMMS/OU Last Updated: 7 April 2003

Forecast/Weather:

The asymmetric squall line from 28 Oct completes its track across Oklahoma (00-5:33 UTC). Following this event, an AP bloom with biological scatterers forms around KOUN.

Radar Operations:

Start time: 00:01 10/29/02 UTC (18:01 10/28/02 local time)
Stop time: 13:08 10/29/02 UTC (7:08 10/29/02 local time)

Radar/Operational Status:

Hydrometeor Classification Algorithm: Warm season

Operational Delivery:

Not applicable.

Snapshots:

Figure 1: AP is apparent in the radar reflectivity data surrounding KOUN after the precipitation has moved out of Oklahoma (9:21 UTC).	Figure 2: High values of ZDR, especially north-northeast of KOUN, indicate the presence of biological scatterers.
Figure 3: The band of higher correlation coefficients (0.70) indicates a more similar mix of scatterers north of KOUN than south of KOUN.	Figure 4: The hydrometeor classification algorithm identifies biological scatterers around KOUN.
