Why Is the Numerical Modeling of Tropical Cyclones So Challenging?

Event Navigation

Tropical cyclones can influence large areas with high winds, heavy rainfall and sometimes storm surge. But despite the spatial scale and severity of their impact, they are driven by a relatively small-scale and meteorologically complex power plant. In order to accurately represent tropical cyclones in numerical models, one must account for processes spanning a broad range of spatial scales, from convection in the eye wall and spiral bands, to air-sea interactions involving sea spray, waves and evaporation, to large-scale weather systems that can exert a significant steering influence. These challenges are exacerbated by the paucity of in-situ observations in the immediate vicinity of most tropical cyclones.

In this talk, Gary Lackmann, a professor in the Department of Marine, Earth, and Atmospheric Sciences, will review some of these scientific and computational challenges and describe some of the techniques being used to overcome them.

The event is free and open to the public. Light refreshments and snacks will be available. There will be an opportunity to meet and greet with colleagues before and after the event.
