A train of four tropical cyclones is lined up in the southern Indian Ocean east of Madagascar (left) on February 12, 2003. This true-color image of the storms was made from observations collected by alternating passes of the Aqua and Terra satellites.
Ocean currents, up to 100 metres (330 ft) in depth from the ocean surface, follow in phase with the east-wind component of the surface winds. In advance, or to the east, of the MJO enhanced activity, winds aloft are westerly. In its wake, or to the west of the enhanced rainfall area, winds aloft are easterly.
The Equatorial Counter Current is an eastward flowing, wind-driven current which extends to depths of 100–150 metres (330–490 ft) in the Atlantic, Indian, and Pacific Oceans. More often called the North Equatorial Countercurrent (NECC) , this current flows west-to-east at about 3-10°N in the Atlantic , Indian Ocean and Pacific basins ...
The South Equatorial Current are ocean currents in the Pacific, Atlantic, and Indian Ocean that flow east-to-west between the equator and about 20 degrees south. In the Pacific and Atlantic Oceans, it extends across the equator to about 5 degrees north.
The South-West Indian Ocean is located within the Southern Hemisphere between the Africa's east coast and 90°E and is primarily monitored by the Meteo France's La Reunion RSMC, while the Mauritian, Australian, Indonesian, and Malagasy weather services also monitor parts of it. [30]
A surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations. [2] Weather maps are created by plotting or tracing the values of relevant quantities such as sea level pressure, temperature, and cloud cover ...
Satellite image of an upper tropospheric cyclonic vortex in the western North Pacific. An upper tropospheric cyclonic vortex is a vortex, or a circulation with a definable center, that usually moves slowly from east-northeast to west-southwest and is prevalent across Northern Hemisphere's warm season.
The aridity of the Sahara Desert and the summer drought of the Mediterranean Basin is due to the large-scale subsidence and sinking motion of air in the system. In its summer position, the high is centered near Bermuda, and creates a southwest flow of hot tropical air toward the East Coast of the United States. In summer, the Azores-Bermuda ...
