Decadal changes of the wintertime tropical tropospheric temperature and their influences on the extratropical climate
A decadal change of the tropical tropospheric temperature (TT) was identified to occur in the winter of 1997. Compared with that in the former period (1979–1996), the wintertime TT was significantly high over ...
