Abstract: In a mathematical model (presented in Part 1), an unstable lapse rate ? and a uniform vertical velocity w0 were imposed upon a horizontal layer of fluid between two porous boundaries. The stability of the nonlinear solutions ...

Abstract: A nonlinear mathematical model of an unstably stratified layer of fluid with an imposed uniform vertical mass flux ? through porous boundaries has shown that, for Rayleigh number R near its critical value Rc for | ? | ≤ ...

Abstract: The relationship of ?open? or ?closed? cellular cloud patterns to large-scale sinking or rising motion is investigated. In particular, it is shown that the open cell patterns typically found behind cold fronts can be ...

Abstract: his study provides a monsoonal link to the rapid Arctic ice melt. Each year the planetary-scale African?Asian monsoonal outflow near the tropopause carries a large anticyclonic gyre that has a longitudinal spread that ...

Abstract: Improved seasonal prediction of sea surface temperature (SST) anomalies over the global oceans is the theme of this paper. Using 13 state-of-the-art coupled global atmosphere?ocean models and 13 yr of seasonal forecasts, ...

Abstract: ter distinguishes the mechanism of tropical convective disturbances, such as a hurricane, from that of the Madden?Julian oscillation (MJO). The hurricane is maintained by organized convection around the azimuth. In a ...
