COMMENT:
|
|
//
|
|
// IPLayer is a Situational Awareness field for environments that are
|
|
// warm aloft (Tw>3C). The goal is to capture deep cloud processes where
|
|
// ice will be melted in the warm layer aloft to liquid, and then fall into a
|
|
// deep, <0C cold air layer and refreeze to sleet instead of fzra. This field checks for
|
|
// Max Tw aloft above the frzlvl, then Max Tw > 3C, and RH>70%i at MaxTw level
|
|
// OB9 modification:
|
|
// Checking for cold surface-based layer depth >1500ft and colder than -5.5 minT in
|
|
// lowest 3 km AGL.
|
|
// Using an image and highlighting over 1500feet but then increasing sleet probs
|
|
// toward and above 2500ft gives the forecaster at least a flag to check further into sounding
|
|
// details. Used in Ptype Family.
