Dynamics and predictability for typhoons

It is hypothesized that "the complex multiscale interaction between environment and vortex" is the key to the changes of typhoon track, intensity and structure, and that "the changes of typhoon track, intensity and structure are internally coordinated given an environmental forcing". Based on this new theoretical assumption this subject systematically studies the challenging 3-7-day prediction of typhoons and predictability in the Northwest Pacific.

Study on the Mechanisms and Key Physical Processes of Tropical Cyclone Intensity Change

Tropical cyclones (TCs）are synotpic weather systems that form overthewarm tropical oceans. After their geneses, TCs are often affectd by complex multi-scale processes among convections, storm scale dynamics and the varying environment. Because of their complexity, 3-7 day forecastis o f TC track, structure and intensity are quite chanlenging, and thus how to imrpove the TC track, intensity and structure 3-7 day in advance is one of the difficult issues in the world.

Data assimilation algorithms for typhoons

Data assimilation plays a critical role in improving the skills of numerical weather prediction by establishing accurate initial conditions. Especially for forecasting tropical cyclones (TCs), multiscale data assimilation algorithm and ensemble sensitivity analysis, strategies combating dynamically inconsistent and imbalanced initial conditions, and effective usage of advanced observations like the satellite radiances, are investigated.

Study on Prediction Technique of 3-7 Day Track, Intensity and Structure of Typhoons

It focuses on solving the difficult 3-7 day long-term typhoon forecast problem and develops some new integrated schemes or algorithms for operational typhoon track, intensity and scale or structure forecast. The results of the project will be directly applied to operational typhoon forecasting in China, improve the ability to forecast 3-7 days of typhoons, and play an active role in national disaster prevention and reduction.
