Impact of the qbo on surface winter climate
WitrynaIt has been widely recognized that the QBO can impact the NH winter stratospheric polar vortex, known as the Holton and Tan (1980) relationship (HT relationship hereafter). Holton and Tan (1980) also proposed a mech-anism whereby this effect occurs: the QBO modifies the latitude of the zero-wind line at 50 hPa from near the Witrynastated. Here we focus on the atmospheric response in early boreal winter (November to December) when the QBO influence is greatest in our model. This period is …
