Below are animations of anomalous diurnal convection. The anomalies represent the OLR for a given hour averaged over a time period minus the daily mean value for that same time period. Loops of 3-hourly data(00,03,06,09,12,18,21) are shown below:
The OLR anomaly fields for the 1999 season were derived using GOES-8 IR data. These fields represent 16km OLR data interpolated to a 0.2deg latlon grid.
The OLR anomaly fields forthe 2001 season were derived using 4km IR data from CPC which has been converted to OLR fields and interpolated to a 0.2deg latlon grid.
