Sentences with phrase «ao nam»
Not exact matches
... or is any AO / NAM trend driven partly by changes in storm track positions themselves being forced by other changes besides specifically AO / NAM (reduced static stability at higher latitudes, reduced lower tropospheric temp gradient, increased gradient in upper troposphere and lower stratosphere, increased humidity, variations in all those with latitude and longitude...)??

The response to the model to varied snow cover did not resemble the PNA pattern but instead was much closer an atmospheric pattern associated with the NAO (North Atlantic Oscillation) or AO / NAM (Arctic Oscillation or Northern Annular Mode).
The NAO and NAM (or AO as some call it) are natural modes of variability.
The NAM has also been known as the Arctic Oscillation (AO), and is closely related to the NAO.
Stratosphere - troposphere interaction: signals of changes in the polar vortex and the Northern Annular Mode / Arctic Oscillation (NAM / AO) are often seen to come from the stratosphere, with the anomalous tropospheric flow lasting up to about two month
More recent work is identifying climate shifts working through the El Niño - Southern Oscillation (ENSO), Atlantic Multidecadal Oscillation (AMO), Pacific Decadal Oscillation (PDO), North Atlantic Oscillation (NAO), Southern and Northern Annular Modes (SAM and NAM), Artic Oscillation (AO), Indian Ocean Dipole (IOD), North Pacific Oscillation (NPO) and other measures of ocean and atmospheric states.
4) Stratosphere - troposphere interaction: signals of changes in the polar vortex and the Northern Annular Mode / Arctic Oscillation (NAM / AO) are often seen to come from the stratosphere, with the anomalous tropospheric flow lasting up to about two months
There is an alternate name for the AO — the Northern Annular Mode (NAM).
Examples are the North Atlantic Oscillation (NAO), the Pacific - North American pattern (PNA), the El Niño Southern Oscillation (ENSO), the Northern Annular Mode (NAM; previously called Arctic Oscillation, AO) and the Southern Annular Mode (SAM; previously called the Antarctic Oscillation, AAO).
