1 Latent Heating in the MJO Computed from 16 years of TRMM Precipitation Radar Observation
Hannah C. Barnes, Robert A. Houze, Jr., and Manuel D. Zuluaga University of Washington 2014 NASA Precipitation Measurements Missions (PMM) Science Team Meeting Embassy Suites - Grand Historic Venue, Baltimore, MD 5 August 2014

2 Identify each contiguous 3D “Storm”
Storm Classification Identify each contiguous 3D “Storm” seen by TRMM PR Convective component Stratiform component Extreme characteristic Contiguous 3D volume of convective echo > 30 dBZ Top height > 8 km “Deep Convective Core (Deep)” Horizontal area > 800 km2 “Wide Convective Core (Wide)” Contiguous stratiform echo with horizontal area > km2 “Broad Stratiform Region (Broad)” “Isolated shallow echo (Shallow)” Echo top > 1 km below freezing level and separate from deeper convection

3 Variability of Precipitating Cloud Population
Central Indian Ocean Southeast West Pacific 2 1.8 1.6 1.4 1.2 1 0.8 0.6 0.4 0.2 1.2 1 0.8 0.6 0.4 0.2 Broad Shallow Wide Deep Broad Shallow Wide Deep Percentage of Pixels Percentage of Pixels MJO Phase MJO Phase Percentage of Pixels that are Intense Echo Features during each Phase Barnes and Houze (2013)

4 Net Heating by Storms Containing Intense Echoes
Storm defined using 2A25 2H25 (SLH) IE y x at height z Σ 2H25 grid point heating = Net Heating by Storms Containing Intense Echoes All Storms

9 Conclusions Heating from Broad Stratiform Regions most variable
Regions differ in terms of convective heating Central Indian Ocean Low-level heating dominates during suppressed stage Wide Convective Cores > Deep Convective Cores Southeast West Pacific Substantial mid/upper-level heating during all phases Wide Convective Cores ≈ Deep Convective Cores Contribution from storms containing wide convective cores >= storms containing deep convective cores Non-classified, mid-level heating important
