Dear all,
<div><br>
</div>
<div>This is reminder of today’s MET seminar, given by <a href="http://nadirjeevanjee.com/">Dr. Nadir Jeevanjee</a> of NOAA’s Geophysical Fluid Dynamics Laboratory. He will speak about “<i>Theoretical constraints on convective clouds”, </i></div>
<div><i><br>
</i></div>
<div>Snacks at 3, talk at 3:15 in EOA 1044. </div>
<div><br>
</div>
<div>The intent is that everyone joins in person, but if you need to attend via Zoom due to a medical reason or approved work off campus, contact Allison Wing for the link. </div>

Dear all,
<div><br>
</div>
<div>Please join us next <b>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>Theoretical constraints on convective clouds</i>” (abstract below).</div>
<div><br>
</div>
<div>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">awing@fsu.edu</a>). </div>
<div><br>
</div>
<div>Graduate students, there will be a free lunch with Dr. Jeevanjee on Thursday. Please RSVP to Allison Wing. </div>
<div>Faculty, please join the speaker and I for drinks and casual conversation at Proof at the Union immediately after the seminar.</div>
<div><br>
</div>
<div><b>DATE: </b>Thursday November 16</div>
<div><b>SEMINAR TIME: </b>Refreshments at 3 PM, Talk 3:15 - 4:15 PM</div>
<div><b>SEMINAR LOCATION: </b>EOA 1044 (Speaker in person)</div>
<div><b>SPEAKER: </b>Dr. Nadir Jeevanjee</div>

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

</div>
<div>We look forward to seeing you there!</div>
