Session 9C Tropical Cyclone Intensity Change in Moderate Shear I

Wednesday, 8 May 2024: 8:30 AM-10:00 AM
Beacon B (Hyatt Regency Long Beach)
Host: 36th Conference on Hurricanes and Tropical Meteorology

Tropical cyclones (TCs) in environments with moderate vertical wind shear exhibit various pathways to intensification and become highly sensitive to the thermodynamic characteristics of the environment. Consequently, there is considerable uncertainty in whether a moderately sheared TC weakens or intensifies through a realignment and/or restructuring process, and forecasting the intensity of such TCs remains a challenge. This session solicits papers pertaining to TC intensity change in moderate vertical wind shear environments. Papers on the following topics are especially encouraged:

- Physical pathways and theoretical frameworks for intensity change in moderate shear;

- Rapid intensification or rapid weakening of moderately sheared TCs;

- Observations and climatological analysis of TCs in moderate shear environments;

- Predictability aspects of intensity change under moderate shear;

- Compound effects of other environmental parameters in moderate shear environments.
