Abstract: We consider here the flow induced by applying a wind stress at the surface of an initially quiescent lake. It is assumed that the Ekman number, based on an eddy viscosity, is small, and that the Rossby number is at most ...

Abstract: A method is given for predicting errors in numerical weather forecasts due to imprecise knowledge of frictional constants, heating, and initial conditions. It is assumed that error bounds are known for these quantities. ...

Abstract: It is assumed that in making a forecast the initial state of the system is known subject to an initial error of measurement. Given an upper bound for the initial error, rigorous bounds are determined for the error of the ...

Abstract: The stability of a barotropic, horizontally sheared, zonal current in a stratified atmosphere is investigated. It is found that several unstable internal modes may exist. These unstable disturbances have longer wave-lengths ...
