The following PDFs contain a forecast product created in support of the Year of Polar Prediction – Southern Hemisphere (YOPP-SH) Targeted Observing Period (TOP). The forecasts were produced by Art Cayette from the Naval Information Warfare Center, Naval Weapons Station, in Charleston, SC. Forecasts are released twice a week – Mondays and Thursdays. They are used to determined when a large scale synoptic system or atmospheric river will be impacting Antarctica to trigger extra radiosonde observing for research study purposes.
Each forecast includes a summary, 300 hPa and IVT maps for three days, a 5 day display of predicted impact regions, and an extended outlook. The forecasts focus on four stations, Davis, Casey, McMurdo, and Palmer in order to target areas such as the Antarctic Peninsula and a large area of East Antarctica into the Ross Ice Shelf.
