Doswell, C.A. III, 2001: Severe convective storms -- An overview. Severe Convective Storms, Meteor. Monogr., 28, no. 50, Amer. Meteor. Soc., 1-26.

3 Severe Convective Storms -- An Overview
February 1, 2006 (Monteverdi) -- Segue from Previous Courses (pp. 1-12) February 8, 2006 (Saussy) -- Severe Convection -- New Material (pp )

4 Severe Convective Storms -- An Overview
Basic Concepts of Deep Moist Convection (DMC) Buoyancy -- Relation to CAPE and the Vertical Equation of Motion

5 Severe Convective Storms -- An Overview

6 Severe Convective Storms -- An Overview
From Metr 201, 401, 402 and 403 the buoyancy equation is obtained by substitution of the equation of state into the vertical equation of motion (below).

7 Severe Convective Storms -- An Overview
CAPE is a measure of the buoyant acceleration experienced by an air parcel integrated from the LFC to the EL

Review -- The Cell as a Building Block in Organized Convective Systems

10 Severe Convective Storms -- An Overview
Revising a concept -- air parcel vs convective bubble

11 Severe Convective Storms -- An Overview
Revising a concept -- air parcel vs convective bubble Modes of convection beyond single cell linear and globular (squall lines and MCSs -- outflows joining) Supercells (single cell outflow) More on above in future classes. Segue to Kathryn
