Climatology of Cyclones, Anticyclones and Storm Tracks: Revision of Concepts
This paper has the finality of describe climatology of extratropical cyclones, anticyclones and storm tracks for the NH and SH. There is a long history of studies on the characteristics of synoptic systems, beginning with classical work on mid-latitude cyclones. For the SH, analyses of pressure data provide extensive statistics of the climatology of synoptic systems. Interestingly, the anticycl...
متن کاملA Diagnostic Comparison of Alaskan and Siberian Strong Anticyclones
Strong anticyclones have a significant impact on the cool season climate over midand high-latitude landmasses as they are typically accompanied by arctic air masses that can eventually move into populated midlatitude regions. Composite analyses of Alaskan and Siberian strong anticyclones based on sea level pressure (SLP) thresholds of 1050 and 1060 hPa, respectively, were performed to diagnose ...
متن کاملA climatology of stratospheric polar vortices and anticyclones
[1] United Kingdom Meteorological Office global analyses from 1991 to 2001 are used to create a global climatology of stratospheric polar vortices and anticyclones. New methodologies are developed that identify vortices in terms of evolving three-dimensional (3-D) air masses. A case study illustrates the performance of the identification schemes during February and March of 1999 when a merger o...
متن کاملDynamics of wind-forced coherent anticyclones in open ocean
1 We numerically study the dynamics of coherent anticyclonic eddies in the ocean interior. For 2 the hydrostatic, rotating, stably-stratified turbulence we use a high-resolution, Primitive3 Equation model forced by small-scale winds in a idealized configuration. Many properties 4 of the horizontal motions are found to be similar to those of two-dimensional and quasi5 geostrophic turbulence. Maj...
متن کاملIntensification of the Southern Hemisphere summertime subtropical anticyclones in a warming climate
[1] The Southern Hemisphere subtropical anticyclones (SAs) are important features of the Earth’s climate. A broad consensus among Coupled Model Intercomparison Project phase 3 and phase 5 climate models suggests an intensification of summer SAs over SH oceans in association with the increase in greenhouse gas concentrations in the atmosphere. Diagnostic and modeling analyses conducted here demo...
