21Meso Call for Papers

The 21st Conference on Mesoscale Processes, sponsored by the American Meteorological Society (AMS) and organized by the AMS Committee on Mesoscale Processes, will be held June 23-26 2025 at the Boise Centre in Boise, Idaho. The conference will be held jointly with the AMS 52nd Conference on Broadcast and Digital Meteorology.

Oral and poster presentations are solicited to understand the processes governing the dynamics of all areas of climate- and weather-related mesoscale phenomena. These areas Include, but are not limited to, observational, theoretical, and modeling studies of:

  • Mesoscale Convective Systems and Convective Organization;

  • Microphysical and Aerosol Effects on Mesoscale Processes;

  • Predictability of Mesoscale Processes and Their Multi-Scale Interactions;

  • Gravity Waves and Turbulence;

  • Orographic Flows and Rainfall;

  • Tropical Cyclones;

  • Extratropical Cyclones and Winter Storms;

  • Data Assimilation and AI/ML Techniques to Improve the Understanding of Mesoscale Processes and Extremes;

  • Results from Recent Field Campaigns (TRACER, PERiLS, and others);

  • The INCUS Mission: Convective Mass Flux, Updraft Dynamics, and Anvils;

  • Communication and Impacts of Mesoscale Hazards (Joint session with 52Broadcast);

  • Other Topics in Mesoscale Processes

 

The INCUS Mission: Convective Mass Flux, Updraft Dynamics, and Anvils  

The upcoming NASA Investigation of Convective Updrafts (INCUS) mission will provide the first ever observations of convective mass flux and its temporal evolution within deep convective storms, along with anvil cloud properties, throughout the tropics and subtropics. These observations and the suite of developing INCUS products will enhance our understanding of the mesoscale processes associated with deep convective clouds. 

Special Session in Honor of Dr. Steven E. Koch

This session seeks contributions on mesoscale gravity waves and bores, mesoscale convective systems, orographic flows, nonclassical fronts, or in short, on any topic that somehow connects to Steve Koch’s pioneering work on improving the understanding of mesoscale processes and advancing mesoscale observing and modeling abilities. A select number of extended (30 min.) invited talks will be chosen, but abstracts for shorter (15 min.) oral presentations and posters are welcomed.

-----------------------------------------------------------------------------------------------------------------------------------------------

We invite presentations related to all aspects of convective storm processes, including convective mass flux (CMF), updraft and downdraft dynamics, convective anvil processes, and cloud radiative feedbacks. Topics of relevance include (but are not limited to) tropical convection, mesoscale environmental controls on CMF, the relationship between CMF and storm properties and features (e.g. cloud anvils, overshooting tops, etc.), and quantifying the links between CMF and extreme weather events in current and future climate scenarios. Studies identifying gaps in our knowledge of these processes are particularly welcome, as are suggestions around the use of INCUS observations and ways in which they may be enhanced. Theoretical, modeling, and observational studies are all encouraged.  

Multiple submissions are allowed by individual authors. However, AMS policy limits participation to one oral presentation each (please note that additional submissions will be assigned as posters). The availability of oral presentations will depend on the number of submissions. When submitting more than one abstract, authors are also asked to specify which abstract they would prefer to be considered for oral presentation. Abstracts should be submitted online by the deadline of Friday, January 30, 2025 at 5:00 PM ET. An abstract fee of $120.00 (payable by credit card) is required at the time of abstract submission (refundable only if the abstract is not accepted). This fee includes the posting of your abstract and the posting of your presentation and its recording (if consented to) on the AMS website.


Authors of accepted presentations will be notified via email by early March 2025. Extended abstracts (file size limit of 10 MB) must be submitted electronically by July 23, 2025 and will be posted on the AMS website. Instructions for formatting these optional extended abstracts will be posted on the AMS website. All abstracts, extended abstracts, and presentations (including the recordings of those who have granted permission) will be made available on the AMS website. For further information, please contact the conference co-chairs: Matthew Brown ([email protected]) and Daniel Kirshbaum ([email protected]).
