Boulder, Colo.: U.S. Dept. of Commerce, National Oceanic and Atmospheric Administration, Environmental Research Laboratories, [] (OCoLC) SESAME: Severe Environmental Storms and Mesoscale Experiment Summary During the spring ofNSF, NOAA, NASA, other Governmental Agencies, and 14 Universities participated in a joint field project called the Severe Environmental Storms and Mesoscale Experiment (SESAME) to learn more about the structure, meso-synoptic processes, and dynamics of severe convective mesoscale.

JDOP () NSSL conducted the Joint Doppler Operational Project to prove Doppler radar could improve the nation's ability to warn for severe thunderstorms and tornadoes. The Severe Environmental Storms and Mesoscale Experiment (SESAME; e.g., LillyAlberty and BarnesAlberty et al.

) was a mesoscale observational program designed to improve our understanding of the influence of the local environment on the generation of these intense cumulus convective systems over the Great Plains of the United States. The Mesoscale Predictability Experiment (MPEX) was conducted from 15 May to 15 June in the central United States.

MPEX was motivated by the basic question of whether experimental, subsynoptic observations can extend convective-scale predictability and otherwise enhance skill in short-term regional numerical weather by: While the large-scale flow establishes environmental conditions favorable for severe weather, processes on the mesoscale initiate such storms, affect their evolution, and influence their environment.

The Mesoscale Predictability Experiment (MPEX) field campaign incorporates enhanced mesoscale observations of the upstream and nearby convective environment to improve the predictability of. The Mesoscale Predictability Experiment (MPEX) is a field program that aims to investigate the predictability of convective storms on the mesoscale.

In particular, it seeks to address the basic question of whether experimental, sub-synoptic observations can Cited by: Two experimental forecasting projects, each called Mesoscale Applications Project (MAP), were conducted jointly by the National Severe Storms Laboratory and the National Weather Service Forecast Office at Norman, Oklahoma, during and Cited by: 4.

As an outgrowth of this recognition, scientists in proposed a multiscale program, the Severe Environmental Storms and Mesoscale Experiment (SESAME; NOAA, ), which was designed to specifically address the vital scale-interaction problem mentioned above.

The Severe Environmental Storms and Mesoscale Experiment (SESAME) (e.g., Lilly ; Alberty and Barnes ; Alberty et al. ) was a mesoscale observational program designed to improve our understanding of the influence of the local environment on the generation of these intense cumulus convective systems over the Great Plains of the United.

As part of the evolution and future enhancement of the Next Generation Weather Radars (NEXRAD), the National Severe Storms Laboratory recently upgraded the KOUN Weather Surveillance Radar Doppler (WSRD) to include a polarimetric by:   Displays from a single Doppler radar collected in two squall-line storms observed during the Oklahoma-Kansas PRE-STORM project conducted in May and June reveal mesoscale-flow patterns in the stratiform rain region of the squall line, such as front-to-rear storm-relative flow at upper levels, a subsiding storm-relative rear inflow at middle Cited by: The mobile project tried to understand and improve prediction of mesoscale and storm-scale processes that produce severe winds in bowing convective systems lasting at least four hours.

The project used aircraft and mobile ground-based instruments to map the thermodynamic and environmental structure of thunderstorm complexes and mature mesoscale. For example, tropical meteorologists participated in the GARP Atlantic Tropical Experiment (GATE) project, and probably much of their best work is yet to come.

The same process is starting to occur around the Severe Environmental Storms and Mesoscale Experiment (SESAME).

Research topics at the National Severe Storms Laboratory. NSSL research helps fulfill NOAA's mission goals through reseearch and development dedicated to improving observations, predictions and warnings of high-impact weather, including tornadoes, severe thunderstorms and flash floods.

VORTEX-SE: Topics & Impacts. The Verification of the Origins of Rotation in Tornadoes EXperiment-Southeast (VORTEX-SE) is a research program to understand how environmental factors characteristic of the Southeastern U.S. affect the formation, intensity, structure, and path of tornadoes in this region.

VORTEX-SE will also determine the best methods for communicating forecast uncertainty of. During this period in time, special mesoscale data were collected over the central portion of the United States as part of the Severe Environmental Storm and Mesoscale Experiment (SESAME).

The results of the simulations are presented following a description of the observed atmospheric behavior during this period and a summary of the model.

The atmosphere in the two sets of EXPs are forced by the same mesoscale sea surface temperature anomaly which resembles the oceanic warm eddy in KE region. The results of these EXPs confirm that under weak background wind conditions, the atmospheric secondary circulation over oceanic eddies is driven by the pressure adjustment process due to.

Tornado activity in the United States has become more variable, particularly over the s, with a decrease in the number of days per year with tornadoes and an increase in the number of tornadoes on these days (medium confidence).Confidence in past trends for hail and severe thunderstorm winds, however, is e models consistently project environmental changes.

The result of convective overturning would appear to be a stabilization of the local density stratification, as manifest by a relaxation of the temperature lapse rate above the boundary layer toward one of a moist-neutral parcel, and (near) elimination of convective available potential energy (CAPE) (e.g., see the review by Bretherton ).In this regard, convective overturning or Cited by: 3.

The Mesoscale Predictability Experiment (MPEX) was conducted within the U.S. intermountain region and high plains during the late spring/early summer of and included the use of the NSF/NCAR GV, along with the new Airborne Vertical Atmospheric Profiling System (AVAPS) dropsonde system and the Microwave Temperature Profiler (MTP) system, as well as several ground.

An Analysis of the Favorable Synoptic and Mesoscale Environments Associated with the January 22nd Tornado Outbreak Introduction The January 22nd tornado outbreak was the deadliest in South Georgia in nearly 17 years. From the pre-dawn hours through mid-afternoon, 4 significant (EF-2 or greater).This new textbook seeks to promote a deep yet accessible understanding of mesoscale-convective processes in the atmosphere.

Mesoscale-convective processes are commonly manifested in the form of thunderstorms, which are fast evolving, inherently hazardous, and can assume a 5/5(2).
