Cyclone phase evolution: Analyses & Forecasts

This page presents historical, analyzed (current), and model-forecast cyclone phase diagrams for northwestern hemisphere cyclones
with the goals of improved structural forecasting, structural transition (subtropical/tropical/extratropical), cyclogenesis, and providing measures of structural predictability.

Please note that these products are experimental and not official forecasts. For official forecasts in the U.S., please refer to the National Weather Service and National Hurricane Center.

Note: ECMWF analyses are provided by TIGGE and delayed by 2-3 days by ECMWF.

To the right are the most recently picked interesting diagrams (in this case a GFS ensemble forecast of the extratropical transition of a
WPAC Typhoon that eventually becomes an intense warm seclusion extratropical cyclone).
