Dear all,
<div class=""><br class="">
</div>
<div class="">Please join us next <b class="">Thursday November 16</b> for a Meteorology seminar, given by Dr. Nadir Jeevanjee of NOAA’s Geophysical Fluid Dynamics Laboratory. He will speak about "<i class="">Theoretical constraints on convective clouds</i>”
(abstract below).</div>
<div class=""><br class="">
</div>
<div class="">Dr. Jeevanjee will be joining us in person in 1044. If you are interested in meeting with him, please contact Allison Wing (<a href="mailto:awing@fsu.edu" class="">awing@fsu.edu</a>). </div>
<div class=""><br class="">
</div>
<div class="">Graduate students, there will be a free lunch with Dr. Jeevanjee on Thursday. Please RSVP to Allison Wing. </div>
<div class="">Faculty, please join the speaker and I for drinks and casual conversation at Proof at the Union immediately after the seminar.</div>

<div class=""><b class="">TITLE: </b><i class="">Theoretical constraints on convective clouds</i></div>
<div class=""><b class=""><br class="">

<div class=""><b class="">ABSTRACT: </b>Convective clouds are central characters in weather and climate, but are governed by a complex interplay of fluid dynamics, thermodynamics, and cloud microphysics which make their gross behavior difficult to understand.
Here we identify constraints on two aspects of convective cloudiness: the convective mass-flux and the density of liquid water within cloudy updrafts. We show that convective mass-flux is constrained to decrease with warming at a rate of 3-4%/K, and that the
density of cloud liquid water is constrained to be about 1/10 the value of boundary layer specific humidity in both present day and warmed climates. Both constraints are verified across a wide hierarchy of models, from pencil-and-paper theory to cloud-resolving
models to global climate models.</div>
