Abstract

Abstract

According to statistical test of ECMWF daily data from winter to summer, the seasonal rapid change (SRC) is found separately in April and June over the Northern Hemisphere. The features of April SRC and June SRC, including the distributions of optimal sensitivity perturbarion(DOSP), the early or late anomaly and the DOSP for each of them are studied based on adjoint sensitivity analysis theory. The results provide us with some new insight into the most significant influential factors of SRC. It also demonstrates the great potential of further applications of this method in oceanic and atmcepherlc circulation diagnostics.
