The Mean Air Flow as Lagrangian Dynamics Approximation and Its Application to Moist Convection
Publisher: American Meteorological Society
Abstract: his paper introduces the Mean Airflow as Lagrangian Dynamics Approximation (MAFALDA), a new method designed to extract thermodynamic cycles from numerical simulations of turbulent atmospheric flows. This approach relies ...
Reconstruction of Thermodynamic Cycles in a High-Resolution Simulation of a Hurricane
Publisher: American Meteorological Society
Abstract: AbstractThe relationship between energy transport and kinetic energy generation in a hurricane is analyzed. The hydrological cycle has a negative impact on the generation of kinetic energy. First, in a precipitating ...
Isentropic Analysis of Convective Motions
Publisher: American Meteorological Society
Abstract: his paper analyzes the convective mass transport by sorting air parcels in terms of their equivalent potential temperature to determine an isentropic streamfunction. By averaging the vertical mass flux at a constant value ...
Atmospheric Overturning across Multiple Scales of an MJO Event during the CINDY/DYNAMO Campaign
Publisher: American Meteorological Society
Abstract: AbstractThis study investigates the atmospheric overturning of the October 2011 MJO event observed during the Cooperative Indian Ocean Experiment on Intraseasonal Variability in the Year 2011 (CINDY)/DYNAMO field experiment ...
Investigating the Relationship between Sea Surface Temperature and the Mechanical Efficiency of Tropical Cyclones
Publisher: American Meteorological Society
Isentropic Analysis of a Simulated Hurricane
Publisher: American Meteorological Society
Abstract: urricanes, like many other atmospheric flows, are associated with turbulent motions over a wide range of scales. Here the authors adapt a new technique based on the isentropic analysis of convective motions to study the ...
Axisymmetric Hurricane in a Dry Atmosphere: Theoretical Framework and Numerical Experiments
Publisher: American Meteorological Society
Abstract: his paper discusses the possible existence of hurricanes in an atmosphere without water vapor and analyzes the dynamic and thermodynamic structures of simulated hurricane-like storms in moist and dry environments. It is ...
Multiscale Atmospheric Overturning of the Indian Summer Monsoon as Seen through Isentropic Analysis
Publisher: American Meteorological Society
Abstract: AbstractThis study investigates multiscale atmospheric overturning during the 2009 Indian summer monsoon (ISM) using a cloud-permitting numerical model. The isentropic analysis technique adopted here sorts vertical mass ...
