Trends in the speed and probability of winter jet stream cores over the Northern Hemisphere were measured for 1958–2007, and related changes in the thermal structure of the troposphere were identified. Eddy-driven jet (EDJ) core speeds and probabilities increased over the midlatitudes (40–60 °N), with changes as large as 15% (speed) and 30% (probability). These increasing trends are collocated with increases in baroclinicity driven by a spatially heterogeneous pattern of height change… CONTINUE READING
