A Wind Speed Probability–Based Error Swath Open
The Joint Typhoon Warning Center (JTWC) generates a tropical cyclone error swath, depicted on each official warning graphic, based on the forecast track, 5-yr mean forecast track errors, and the size of the largest forecast 34-kt (1 kt ≈ 0…

Recommendations for improved tropical cyclone formation and position probabilistic Forecast products Open
Prediction of the potentially devastating impact of landfalling tropical cyclones (TCs) relies substantially on numerical prediction systems. Due to the limited predictability of TCs and the need to express forecast confidence and possible…

Deterministic Rapid Intensity Forecast Guidance for the Joint Typhoon Warning Center’s Area of Responsibility Open
Intensity consensus forecasts can provide skillful overall guidance for intensity forecasting at the Joint Typhoon Warning Center as they provide among the lowest mean absolute errors; however, these forecasts are far less useful for perio…

ProxyVis—A Proxy for Nighttime Visible Imagery Applicable to Geostationary Satellite Observations Open
Visible satellite imagery is widely used by operational weather forecast centers for tropical and extratropical cyclone analysis and marine forecasting. The absence of visible imagery at night can significantly degrade forecast capabilitie…

A Rapid Intensification Deterministic Ensemble (RIDE) for the Joint Typhoon Warning Center’s Area of Responsibility Open
The Rapid Intensification Deterministic Ensemble (RIDE) is an operational method used to estimate the probability of tropical cyclone rapid intensification in the Joint Typhoon Warning Center’s area of responsibility. Inputs to RIDE are cu…

Track forecast: Operational capability and new techniques - Summary from the Tenth International Workshop on Tropical Cyclones (IWTC-10) Open
In this paper, we summarize findings from the Tenth International Workshop on Tropical Cyclones (IWTC-10) subgroup on operational track forecasting techniques and capability. The rate of improvement in the accuracy of official forecast tra…
