Properties of the Sea Breeze Front as Shown by a Numerical Model
Publisher: American Meteorological Society
Abstract: A simple model of the sea breeze is integrated numerically. If the total beat input into the air is kept constant, the speed of the sea breeze front is found to be independent of the vertical distribution of the temperature ...
Consistent Boundary Conditions for Numerical Models of Systems that Admit Dispersive Waves
Publisher: American Meteorological Society
Abstract: In numerical computation it is often necessary to truncate the region of interest and formulate appropriate boundary conditions. A way of using the Sommerfeld radiation boundary condition for a certain class of initial ...
A Numerical Dynamical Instability
Publisher: American Meteorological Society
Abstract: Errors in the numerical analog to a simple convection model can lead to an instability, even though existing methods of analysis predict that the scheme is stable. The solutions obtained from a number of finite difference ...
An Open Boundary Condition for Models of Thermals
Publisher: American Meteorological Society
Abstract: Numerical models of thermals usually introduce a closed box within which convection occurs. A boundary condition which allows inflow and outflow through the edges of the computational domain is discussed. The results of ...
Marine Atmospheric Boundary Layer Circulations Forced by Gulf Stream Sea Surface Temperature Gradients
Publisher: American Meteorological Society
Abstract: The Penn State/NCAR mesoscale model is initialized with calm winds, a barotropic temperature pattern, and a uniform surface pressure in studies of the response of the marine atmospheric boundary layer (MABL) to realistic ...
Guidelines for Reduced-Order Thermal Modeling of Multifinger GaN HEMTs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The increasing demand for tightly integrated gallium nitride high electron mobility transistors (HEMT) into electronics systems requires accurate thermal evaluation. While these devices exhibit favorable electrical ...
