instantaneously by lidars and dropsondes to verify that the flow sampled by the P3 was almost steady. Interpreting the P3 data as an approximately instantaneous snapshot of the flow in a vertical plane above the axis of the Wipptal, further analysis of the P3 observations of velocity and potential temperature reveals evidence of significant subsidence at the level of the inversion capping the high-speed flow. 2.

region ( Chen and Frank 1993 ; Dolling and Barnes 2012a ). An observational study by Kerns and Chen (2015) showed that subsidence warming associated with MCSs can contribute directly to development of the warm core in TC genesis. About 60% of all TC genesis events in the North Atlantic from 1948 to 2010 involved a varying degree of baroclinicity ( McTaggart-Cowan et al. 2013 ). In the Western Caribbean Basin and Gulf of Mexico, TC genesis often occurs in unfavorable environments, with upper

temperature inversion associated with the descending branches of the Hadley circulation (e.g., Albrecht et al. 1995 ; Norris 1998a ; Wood and Hartmann 2006 ). Both inversion strength and subsidence weaken farther west in the downstream region of the trade winds, and the stratus and stratocumulus eventually transition to scattered trade cumulus, which have a more minor cooling effect. These trade cumulus often occur within a deep, decoupled MBL ( Albrecht et al. 1995 ; Norris 1998a ; Wood and Hartmann

subsidence drying along trajectories is critical to satisfactorily simulating the tropical climate. Salathé and Hartmann (1997) present a trajectory analysis of upper-tropospheric humidity (UTH) and show that the variation of UTH along trajectories provides a simple explanation of the horizontal moisture distribution away from convection. Similar studies by Pierrehumbert (1998) and Soden (1998) have supported these results. The trajectory analysis separates the effect of large-scale advection on

, active sea breeze circulations, and large surface energy fluxes, and it suggests that there is a dynamic control on convection. This paper tests the hypothesis that topographic contrasts within the region act to suppress convection. Specifically, it is proposed that summertime heating on the Zagros Plateau leads to a seasonally persistent temperature contrast between the atmosphere above the plateau and that above the neighboring MEP. The temperature contrast, in turn, influences winds and subsidence

” convective structures, including updraft, subsiding shell, environmental subsidence, and others. “Coherent structures” are widely used to represent a distinct and dominant turbulent flow structure in engineering and geoscience communities ( Robinson 1991 ; Haller and Yuan 2000 ; Farge et al. 2001 , 2006 ; Finnigan et al. 2009 ; Beron-Vera et al. 2015 ; Richter and Sullivan 2014 ). In this study, we call coherent structures the part of the flow that explains most of the vertical transport in the
