1. Introduction This paper is concerned with the dynamics of meridional eddy momentum transport in the tropical troposphere. While early paradigms of tropical momentum transport envisioned a nearly inviscid Hadley cell decelerated by Rossby waves of extratropical origin, Lee (1999) showed that in fact, the westerly eddy forcing compensates the deceleration by the off-equatorial Hadley cell in the deep tropics. As this eddy forcing plays a key role in theories of equatorial superrotation

1. Introduction Mesocale convective systems (MCSs) in the tropics connect the low atmospheric levels to the free troposphere, through the vertical transport of mass, water, and momentum. Their extended upper-level cloud decks have a strong impact on the tropical radiative budget (e.g., Ramanathan and Collins 1991 ; Machado and Rossow 1993 ; Wilcox and Ramanathan 2001 ; Del Genio and Kovari 2002 ; Roca et al. 2005b ; Del Genio et al. 2005 ). These convective systems also dominate the water

1. Introduction and background Throughout the tropics and subtropics, topography has profound influences on the distribution of rainfall. These influences are particularly striking as characterized from space by the Tropical Rainfall Measurement Mission (TRMM)'s precipitation radar (PR). High-resolution climatologies from the TRMM PR show tight relationships between topographic features and both the intensity and diurnal phasing of rainfall down to scales of a few kilometers ( Nesbitt and

horizontal scale in at least one direction.” Here the definition is constrained by the size and intensity of the precipitation created within it. Convective intensity and/or rainfall measurement is a means of distinguishing the distribution of systems that produce the bulk of the heat, momentum, and moisture fluxes in the Tropics and subtropics (i.e., quantifying the “hot towers,” Riehl and Malkus 1958 ). Large-scale rainfall measurement with ground- or aircraft-based radars or gauge data is not

similar to that used by Yan et al. (2014) but uses multiyear global satellite data instead of long-term ground-based measurements made at one location. We examine the systematic changes in CRF with increasing aerosol loading over the entire tropics, where deep convective clouds are more plentiful than at higher latitudes and where different types of aerosols under varying meteorological conditions are present. These systematic changes are referred to as aerosol-mediated changes in CRF (AMCRF

, peak updrafts were observed above the 10-km level and land-based and sea-breeze convection had higher Z e than did oceanic and tropical-cyclone convection ( H10 ). The spatial coverage of ground radars and aircraft campaigns is very limited. It is not clear from past studies how the vertical profiles of hydrometeors in active Cb clouds compare in different parts of the tropics. This study is aimed at filling this gap in knowledge, and the main objective is to document the vertical structure of Z
