Severe Convective Storms: Key Concepts and Review

Learn about deep moist convection, buoyancy, and convective storm components in this comprehensive overview. Explore the basics of buoyancy, CAPE, and convective systems for a deeper understanding. Review critical elements like LCL, LFC, EL, and the cell structure, and revise concepts of air parcels and convective bubbles. Discover different convection modes like squall lines, MCSs, and supercells. Get ready to delve into advanced topics in future sessions.

  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. 13-23)

  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

  8. Severe Convective Storms -- An Overview Review LCL, LFC, EL, CT, CCL

  9. Severe Convective Storms -- An Overview • 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
