Impact of atmospheric convectively coupled equatorial Kelvin waves on upper ocean variability
Convectively coupled Kelvin waves (CCKWs) are atmospheric weather systems that propagate eastward along the equatorial wave guide with phase speeds between 11 and 14ms . They are an important constituent of the convective envelope of the Madden-Julian oscillation (MJO), for which ocean-atmosphere interactions play a vital role. Hence, ocean-atmosphere interactions within CCKWs may be important ...
متن کاملStructure of AGCM-Simulated Convectively Coupled Kelvin Waves and Sensitivity to Convective Parameterization
A study of the convectively coupled Kelvin wave (CCKW) properties from a series of atmospheric general circulation model experiments over observed sea surface temperatures is presented. The simulations are performed with two different convection schemes (a mass flux scheme and a moisture convergence scheme) using a range of convective triggers, which inhibit convection in different ways. Increa...
متن کاملThe Influence of Amazon Rainfall on the Atlantic ITCZ through Convectively Coupled Kelvin Waves
Using outgoing longwave radiation (OLR) and Tropical Rainfall Measuring Mission (TRMM) daily rain-rate data, systematic changes in intensity and location of the Atlantic intertropical convergence zone (ITCZ) were detected along the equator during boreal spring. It is found that the changes in convection over the tropical Atlantic may be induced by deep convection in equatorial South America. La...
متن کاملConvectively Coupled Kelvin Waves in an Idealized Moist General Circulation Model
The dynamics of convectively coupled Kelvin waves and their dependence on convection scheme parameters are studied within a simplified moist general circulation model. The model consists of the primitive equations on the sphere over zonally symmetric aquaplanet, slab mixed layer ocean boundary conditions, and idealized physical parameterizations including gray radiative transfer and a simplifie...
متن کاملModulation of radiative heating by the Madden‐Julian Oscillation and convectively coupled Kelvin waves as observed by CloudSat
[1] The vertical distribution of radiative heating affects the moist static energy budget and potentially the maintenance and propagation of the Madden‐Julian Oscillation (MJO). This paper usesCloudSat data to examine the radiative heating climatology in the tropics and the vertical structure of its modulation by the MJO and convectively coupled Kelvin Waves (KWs). Composites of active regions ...
