Surface Wave Impact When Simulating Midlatitude Storm Development

A Linear Stochastic Model of a GCM’s Midlatitude Storm Tracks

A linear stochastic model is used to simulate the midlatitude storm tracks produced by an atmospheric GCM. A series of six perpetual insolation/SST GCM experiments are first performed for each month. These experiments capture the ‘‘midwinter suppression’’ of the Pacific storm track in a particularly clean way. The stochastic model is constructed by linearizing the GCM about its January climatol...

The Role of Stationary Eddies in Shaping Midlatitude Storm Tracks

Transient and stationary eddies shape the extratropical climate through their transport of heat, moisture, and momentum. In the zonal mean, the transports by transient eddies dominate over those by stationary eddies, but this is not necessarily the case locally. In particular, in storm-track entrance and exit regions during winter, stationary eddies and their interactions with the mean flow dom...

Modulations in the Leading Edges of Midlatitude Storm Tracks

Downstream development is a term encompassing a variety of effects relating to the propagation of storm systems at midlatitude. We investigate a mechanism behind downstream development and study how wave propagation is affected by varying several physical parameters. We then develop a multiple scales modulation theory based on processes in the leading edge of propagating fronts t o examine the ...

Storm Water Extended Release for Low Impact Development

Storm water detention has been widely used for on-site runoff release control. The required storm water detention volumes are often determined by the pre-selected release rates for various design events. When a low release rate is selected, the basin stores more storm water volume than required and it results in an insufficient base flow for the downstream habitats. When a high release is selec...
