Thunderstorms Thermodynamics

What to look for:

- Determine how temperatures and dew points are changing at the surface.

- Look for tongues of maximum dew points and theta-e.

Surface

Low level: 850 hPa

What to look for:

- Low level jet stream

- Moisture convergence

Tips:

Low-level jet streams (or nocturnal low-level jets) increase deep, moisture convergence via warm and moist advection and enhance low-level vertical wind shear.
