Did you know that the weather at the surface of the Earth is just echoes of those processes that occur in the upper layers atmosphere? For this reason, scientists pay significant attention. climatic changes not only in the surface layer, but also on heights.
In the tropics at an altitude of more than ten kilometers, about once every two year, there is a change in the prevailing winds. Strong blow for two years winds of east directions, and two years – west. These changes, which are sometimes compared with the heartbeat of the planet’s atmosphere, scientists called quasi-two-year oscillations.
Over the past six decades the range of these fluctuations significantly weakened. Computer modeling allowed scientists associate this with climate change and increased concentration greenhouse gases in the atmosphere. “This is the first demonstration systematic long-term trend in quasi-biennial fluctuations, “said study co-author Kevin Hamilton.
