Oceanic Convection Diagnosis and Nowcasting
• Federal Aviation Administration (FAA) and National Aeronautics and Space Administration (NASA) sponsors– Oceanic aviation community– Collaboration with Naval Research Laboratory and
Massachusetts Institute of Technology Lincoln Laboratory
• Developing oceanic diagnosis and nowcasting products– Few derived products available for oceanic aviation
• Convective Diagnosis Oceanic (CDO)– GOES-based detection of convection– Fuzzy logic combination of 3 algorithms:
• CTOP: NRL Cloud top height• CldClass: NRL Cloud classification• GCD: Global Convective Diagnosis
• Convective Nowcast Oceanic (CNO)– Extrapolation of CDO using an object tracker– 0-2 hour nowcasts now; longer term nowcasts/forecasts later
• Gulf of Mexico domain - extend to Pacific domain soon
NRL Cloud Top Height (CTOP)
• Cloud IR temperature converted to heights– Global Forecast System (GFS) model sounding
• Temperature matched to pressure level
• Pressure level converted to height via Standard Atmosphere
