  • Description:
    UtiIity of 1000-500-mb thickness in forecasting precipitation type can be enhanced significantly by also considering the mean lapse rate in that layer. This can be done readily by relating thickness to 500-mb temperature. The 500-mb temperature is a relatively easy parameter to forecast in comparison to the uncertainty of temperature forecasts for lower levels. The paradox is developed that inclusion of 500-mb temperature produces a diametrically opposite effect to that which might be expected.
