 At odds with global warming trends, surface air temperature over large subtropical Eurasia continent in spring March exhibits unique strong cooling over the last half century. The cause for this cooling is shown to be related to Winter (DJF) North Atlantic Oscillation (W-NAO). Positive values of W-NAO provoke cooling signals in northern Africa continent simultaneously from surface to tropopause. The W-NAO generated signals barotropically extend eastward over most of subtropical Eurasia and reaches eastern China in March.
