These event statistics also allow us to explore relationships between the statistical properties of cirrus events to other parameters. Currently we are using the NCAR/NCEP reanalysis data to represent the large-scale meteorology of the SGP region during the study period. Using reanalysis data we show the meteorological anomalies during cirrus events from the seasonal and inter-annual means. These anomalies are found by taking the difference between the mean meteorology occurring on days when cirrus events are present, and the seasonal and inter-annual meteorological means. Results of this analysis and implications for the parameterization of cirrus in climate models will be discussed in this paper.
