This paper discusses some results of the study of eddy heat fluxes in the vicinity of a subtropical jet stream. Many large-scale dynamical phenomena in the Earth’s atmosphere are associated with Rossby wave propagation and collapse processes. Here we focus on regions of countergradient eddy heat flu...
