Can we predict the likelihood of a long-lived atmospheric bore? It seems trivial to study pretty waves in the atmosphere (no it doesn’t!), but observations testify that the connection between atmospheric bores and sustained nocturnal convection are not innocuous. For this very reason, Plains Elevated Convection at Night (PECAN), which will be in full force next month, is to probe undular bores over the PECAN domain associated with nocturnal outflows. And although our research suggests that atmospheric bores appear to be ubiquitous features of the nocturnal environment, no clever forecast suite is in place to guide ground crew to locations favorable for data collection of bores. To assist forecasters during PECAN, a bore-forecasting tool has been developed. Based on hydraulic and linear wave theory, the likelihood of a long-lived atmospheric bore developing is assigned a simple low-medium-high scale. Discussions of possible pitfalls are discussed.

Visitor parking is available for all University visitors. However, faculty/staff/students must have a current multi-purpose parking permit. Additional parking is available at the Lloyd Noble Center (LNC) for those individuals who do not have a parking permit. You do not need a permit to park in one of 1,200 spaces reserved for CART bus riders, although you must ride the CART shuttle to park in the reserved area. This area is on the north central side of the Lloyd Noble Center. Elsewhere at the LNC, permits are required.

The University of Oklahoma is a smoke-free / tobacco-free campus.
