Observed Storm Track Dynamics in Drake Passage

Storm Track Dynamics

This paper reviews the current state of observational, theoretical, and modeling knowledge of the midlatitude storm tracks of the Northern Hemisphere cool season. Observed storm track structures and variations form the first part of the review. The climatological storm track structure is described, and the seasonal, interannual, and interdecadal storm track variations are discussed. In particul...

Tectonic reconstructions for paleobathymetry in Drake Passage

Geostrophic transport through the drake passage.

Geostrophic velocity and transport of water in the Drake Passage relative to a newly defined zero reference layer indicate that the circumpolar current is basically north of 59 degrees S, with its axis north 57 degrees S, and that the total volume transport exceeds 200 x 10(6) cubic meters per second. The calculated geostrophic velocities are consistent with results of descriptive water-structu...

storm track dynamics in anomalous winter 2007-2008 from energetic perspective

climatological study of the mid-latitude storm tracks was investigated using the daily global forecast system (gfs) and the national centers for environmental prediction (ncep) reanalysis data sets from 1948 to 2008 winter seasons. in anomalous winter 2007-2008, decreasing of eddy kinetic energy along with the reduction of eddy available potential energy upstream of atlantic storm track are rel...

Seasonal variability of upper ocean heat content in Drake Passage

[1] Mixed-layer depth (MLD) is often used in a mixed-layer heat budget to relate air-sea exchange to changes in the near-surface ocean temperature. In this study, reanalysis heat flux products and profiles from a 15 year time series of high-resolution, near-repeat expendable bathythermograph/expendable conductivity-temperature-depth (XBT/XCTD) sampling in Drake Passage are used to examine the n...
