Abstract: A cloud simulation model that is based on a Monte Carlo method was developed for testing and designing automatic ceilometer systems. With this model, cloud plan views and profile views an generated for several different ...

Abstract: A computer simulation program was used to investigate the sampling problems that are associated with using automated instrument systems to determine cloud amount. The simulated cloud conditions were generated in the computer ...

Abstract: Twenty cases of jet stream cirrus clouds observed in TIROS photographs over the United States are related to the atmospheric wind field. The orientation of features such as shadow lines, sharp-edged cirrus sheets, cirrus ...

Abstract: Distributions of relative vorticity and balanced height are computed from the cloud velocities associated with the cloud structure of an extratropical cyclone over the continental United States during a three-day period ...
