High-resolution idealized simulations of TC genesis

surface vortex formation

Azimuthally averaged wind fields show contraction and intensification of the

mid-level vortex in the 24 hours before genesis

These changes should be visible to NIS radar – even if individual VHTs are not

slide2
How can we evaluate or quantify the changes leading to genesis?One way may be through energy efficiency analyses of the wind field:

6 hours before genesis

24 hours before genesis

Kinetic energy efficiency (KEE) measures the fraction of latent heat energy

released in convection that is converted into kinetic energy of the vortex wind field.

This type of analysis may provide additional predictive power into genesis

and rapid intensification beyond what a forecast model can provide
