|Abstract:||The relation between the air-sea heat ﬂuxes in the Aegean Sea and the total precipitable water (TPW) over Europe and North Africa is investigated. An one-point linear correlation between the components of surface heat exchange and TPW is employed. During winter and for the shortwave radiation, a dipole of opposite correlation (see-saw teleconnection), is observed between the northeast Europe and the East Mediterranean Sea. This pattern is inverted for the longwave radiation and especially during the summer is limited to a strong positive south pole. Both spatial correlation patterns underline the inﬂuence of cloudiness during the winter season and the speciﬁc humidity during summer on the radiative ﬂuxes behavior. Regarding the turbulent air-sea heat ﬂux components – latent and sensible heat – the correlation pattern is enhanced. The winter pattern exhibits positive correlation over Europe with the highest values (r > 0.75) over the Balkan Peninsula. The identiﬁed correlation patterns, although they remain dominant, weaken during the summer. The herein ﬁndings suggest that the stronger relation between the TPW and the turbulent ﬂuxes is regulated by the wind regime|
