The Atmospheric General Circulation and Its Variability
Progress in understanding the general circulation of the atmosphere during the past 25 years is reviewed. The relationships of eddy generation, propagation and dissipation to eddy momentum fluxes and mean zonal winds are now sufficiently understood that intuitive reasoning about momentum based on firm theoretical foundations is possible. Variability in the zonal-flow can now be understood as a ...
متن کاملEstimating Atmospheric Visibility Using General-Purpose Cameras
There is a growing interest in using general-purpose cameras to monitor a variety of physical phenomenon. In particular, a number of visibility camera networks have recently been deployed to complement traditional means for estimating atmospheric visibility. However, the images from these cameras have so far only been used to perform qualitative analysis. This work investigates image processing...
متن کاملThe atmospheric general circulation: Some unresolved issues
Several questions concerning the general circulation for which satisfactory answers are not yet available are discussed. The focus is on the zonal mean heat balance, since problems in our understanding of this balance are a fundamental limitation on our ability to model climate and climate change. The questions are: How strong is the atmosphere’s poleward heat transport? What are the relative r...
متن کاملEstimation and Analysis of Caspian Region's Future Rainfalls by Using General Atmospheric Circulation Models.
In recent years, the severe fluctuations in precipitation have affected various parts of the country. On the southern coasts of the Caspian Sea, precipitation as one of the important climatic parameters has undergone changes due to global climate change. In the present study, we tried to evaluate the effect of climate change on rainfall in this region by applying a suitable model. In this study...
متن کاملAtmospheric Feedbacks over the Tropical Pacific in Observations and Atmospheric General Circulation Models: An Extended Assessment
The dynamical and radiative feedbacks from the deep convection over the tropical Pacific are quantified using ENSO signal in that region for both the observation and 16 climate models. Different from a previous analysis, we recognize the nonlinear relationship between deep convection and SST over that region, and perform the evaluation using the data from the warm phase and the cold phase separ...
