The mean meridional circulation and midlatitude ozone buildup
The wintertime ozone buildup over the Northern Hemisphere (NH) midlatitudes and its connection with the mean meridional circulation in the stratosphere are examined statistically on a monthly basis from October to March (1980–2002). The ozone buildup begins locally in October with positive total ozone tendencies over the North Pacific, which spread eastward and westward in November and finally ...

متن کامل5. the Mean Meridional Circulation
(3) Here the square brackets denote zonal means, RΤ is the net radiation at the top of the atmosphere, and a time average has been used to eliminate the tendency term. Eq. (3) expresses the requirement of total energy balance for a “ring” of air along a latitude circle. By further integration of (3) with respect to latitude, we can obtain the meridional energy transport by the atmosphere, with ...
متن کاملOn the Annual Variation of the Monthly Mean Meridional Circulation
Data for a 5-yr period from a dense network of upper air stations have been used to determine the annual cycle in the mean meridional circulation north of 15's. Only during the transition months April, May and October, November is there some degree of symmetry with respect to the Equator. During the other months of the year, the Hadley cell of the winter hemisphere with a maximum strength of ab...
متن کاملMeridional Circulation and the Solar Magnetic Cycle
The Sun’s magnetic cycle manifests itself in an year periodic variation in the number of sunspots seen on the solar surface and a periodic reversal in the polarity of its large-scale magnetic fields. Exploring the origins of this magnetic cycle can unravel the physical mechanisms at work in the interior of magnetized stars like the Sun. Such studies are also important for understanding how the ...
