<div><b>TITLE: </b><span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);"><i>Radiative Feedbacks in Tropical Convective Organization and the Madden-Julian Oscillation</i></span></div>
<div><br>
</div>
<div><b>ABSTRACT: </b><span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">The presence of high-altitude anvil clouds produced by tropical deep convection imposes radiative heating on the surface and the atmosphere, which modulates the Earth’s energy
budget. These cloud-radiative effects (CREs) were proposed to support the organization of convective systems themselves which produce high clouds. At the same time, we also speculate that convective organization feeds back on modulating the CREs. Such convective-radiative
feedback involving the two-way interaction between convective organization and CREs is not well understood. We ask the following questions: What determines the strength of the convective-radiative feedback? And how do the CREs promote convectively coupled
variabilities in the observed tropics? The presentation will show our studies attempting to tackle these questions using a set of observation-derived data products, including retrievals using spaceborne satellites, ground-based precipitation radar, and reanalyses.</span></div>

</div>
<div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">Our findings suggest that the strength of the radiative feedback changes with space and time, and may be dependent on the organization of convection. Stronger feedback tends to be coupled with a higher
degree of mesoscale convective organization, further supported by higher sea surface temperature and stronger low-level wind shear. How radiative feedback helps maintain a dominant mode of tropical intraseasonal variability, the Madden-Julian oscillation,
is examined as an example showing how such mesoscale-modulated radiative feedback may have an upscale influence on atmospheric variability at larger scales.</div>
