Two years of TOPEX/POSEIDON altimeter data have successfully been used to study the mesoscale field in the Mediterranean and to investigate the seasonal and year-toyear variability of the sea level and eddy statistics in this basin. The mesoscale field described by TOPEX/POSEIDON revealed a strong, but subbasin dependent, seasonal signal. Year-toyear variations are also evident in terms of both...

The Atlantic Tradewind Ocean-Atmosphere Mesoscale Interaction Campaign (ATOMIC) took place in January–February, 2020. It was designed to understand the relationship between shallow convection and large-scale environment trade-wind regime. A Lagrangian large eddy simulation, following trajectory of a boundary-layer airmass, can reproduce transition trade cumulus organization from “sugar” “flower...

Five characteristic, low-level, large-scale dynamical patterns associated with tropical cyclogenesis in the western North Pacific basin are examined along with their capacity to generate the type of mesoscale convective systems that precede genesis. An 8-yr analysis set for the region is used to identify, and create composites for, the five characteristic patterns of monsoon shear line, monsoon...

Fluctuating hydrodynamics based techniques have been developed in recent years for the simulation of Brownian motion of particles. These “mesoscale” simulation tools are viable approaches for problems where molecular dynamics simulations may be deemed expensive. We have developed a rigid constraint–based formulation where the key idea is to assume that the entire domain is a fluctuating fluid. ...

Numerical models such as the Mesoscale Model 5 (MM5) or the Weather Research and Forecasting Model (WRF) are used by meteorologists in the prediction and the study of hurricanes. The outputs from such models vary greatly depending on the model, the initialization conditions, the simulation resolution and the computational resources available. The overwhelming amount of data that is generated ca...
