The nao troposphere–stratosphere connection
WebNov 29, 2024 · During winter, the boreal stratosphere couples with the underlying troposphere in two pathways: bottom-up and top-down. Often it undergoes different extreme circulation states: cold events with a strong polar vortex and zonal mean westerlies (polar-night jet); and warm events with a weakening or a breakdown of the polar vortex and zonal … WebDec 3, 2009 · The NAO troposphere-stratosphere connection.
