    Purchase Interhemispheric Water Exchange in the Atlantic Ocean, Volume 68 - 1st Edition. Print Book & E-Book. ISBN , We present estimates of total nitrogen and total phosphorus fluxes in rivers to the North Atlantic Ocean from 14 regions in North America, South America, Europe, and Africa which collectively comprise the drainage basins to the North Atlantic. The Amazon basin dominates the overall phosphorus flux and has the highest phosphorus flux per area.

      A low pressure area forms at the surface and a region of clouds forms at altitude. The air eventually stops rising and spreads north and south towards the Earth's poles. About miles from the equator, the air falls back to Earth's surface blowing towards the pole and back to the equator. Summary. The Earth's ocean-atmosphere system was experiencing a weak El Niño during March The upper-level circulation was quite active this month, with the long-wave pattern shifting from a long-wave trough in the western contiguous United States (CONUS) and a long-wave ridge in the East, to a long-wave ridge in the West and trough in the East. Short-wave troughs migrating through the.

    The tropical disturbances that affect affect the Atlantic Ocean, Caribbean Sea, and the Americas, mostly form over: western Africa, south of the Sahara Desert. Why do surface wind speeds increase toward the center of a hurricane? Using Meteosat data and ECMWF analyses, we examine easterly waves and their relation with the cloudiness over West Africa and the tropical Atlantic Ocean .

These currents, which are associated with intense coastal upwelling and low sea surface tem-peratures, feed the westward North and South Equatorial Currents respectively.

This division (Longhurst et al., ) was based on historical information of general surface circulation patterns observed in this by: of the West African and tropical Atlantic climate. They are known both to modulate the daily rainfall over West Africa (e.g., Reed et al. ) and to initiate most At-lantic tropical cyclones (e.g., Landsea et al.

De-spite their importance, very little is known about the detailed aspects of their life cycle, including genesis.

The influence of South Africa’s latitudinal position South Africa is situated between the latitudes 22°S and 33°S. This means that our climate is dominated by the belt of subtropical highs.

The three high that affect South Africa are the South Atlantic High, Kalahari High and the South Indian High. Upon reaching the east coast of North America, tropical storms and hurricanes are most likely to move in this general direction: A.

north. south. east. west. The primary over-riding requirement for hurricane development is: D. take a week to ten days to move across the Atlantic Ocean. The tropical Atlantic is home to multiple coupled climate variations covering a wide range of timescales and impacting societally relevant phenomena such as continental rainfall, Atlantic hurricane activity, oceanic biological productivity, and atmospheric circulation in the equatorial Pacific.

The tropical Atlantic also connects the southern and northern branches of the Atlantic meridional. The second-largest ocean on Earth, the Atlantic drives our weather patterns, including hurricanes, and is home to many species from sea turtles to dolphins.

The tropical monsoon climate, designated by the Köppen climate classification as "Am", is found in the southern part of the country. This climate is influenced by the monsoons originating from the South Atlantic ocean, which is brought into the country by the (maritime tropical) MT airmass, a warm moist sea to land seasonal warmth and high humidity gives it a strong tendency to.

Because Bonan () evaluated the global aspects of the model without much attention to the Atlantic, and because Fu et al. () evaluated the model only in the Amazon region, we will reexamine the capabilities of the model to simulate the annual cycle in the Atlantic region (Fig.

1), comprising the tropical Atlantic, South America, and Africa. The OLR composite anomalies calculated for 5 days before the days of positive phase in South Africa (Figs. 2b, 3b, and 4b) are used only to confirm the results of the correlations, and to add information about regions within or nearby South America (e.g., the Atlantic) where precipitation data are not available and anomalous convection might be.

The Pacific Ocean regions have a greater influence and are more widespread over SCSA; the Atlantic Ocean regions have an influence only over the northwestern and the southeastern parts of SCSA.

In general, the relationship with the equatorial and tropical Atlantic and Pacific Oceans is of the type warm–wet/cold–dry, whereas the subtropical. The season before we had sailed our foot cutter Moose across the Indian Ocean and cruised Madagascar (“Pirogues & Dhows, December ) and Mozambique (“A Passage to Africa”, May ) before settling down at the Zululand Yacht Club in Richard’s Bay, at the top of South Africa’s east coast.

To continue down to Cape Town, we would have to sail the notorious Wild Coast. Sahara, (from Arabic ṣaḥrāʾ, “desert”) largest desert in the world. Filling nearly all of northern Africa, it measures approximately 3, miles (4, km) from east to west and between and 1, miles from north to south and has a total area of some 3, square miles (8, square km); the actual area varies as the desert expands and contracts over time.

Regions of Enslavement for the Trans-Atlantic Slave Trade. Alistair Boddy-Evans. Enslaved Africans for the Trans-Atlantic Slave Trade were initially sourced in Senegambia and the Windward Coast.

Around the trade moved to west-central Africa (the Kingdom of the Kongo and neighboring Angola). The tropics are regions of the Earth that lie roughly in the middle of the tropics between the latitude lines of the Tropic of Cancer and the Tropic of tropics include the Equator and parts of North America, South America, Africa, Asia, and Australia.

The tropics account for 36 percent of the Earth's landmass and are home to about a third of the world's people. The brown mussel is native to the tropical and sub-tropical regions of the Atlantic Ocean.

It is found in waters off the west coast of Africa and the coast of South America up to the Caribbean. It is accidentally introduced as an invasive species to the coast of Texas via the boat hulls and water ballasts of ships from Venezuela.

In this study, we will focus on the South America and Atlantic region, although the central Pacific Ocean is also an interesting region to be examined in future studies.

To be more specific, the region that we will focus on is 15°S–15°N, 80°W–0° (pink box in phase 1 of Fig. 2).The region of West Africa includes the southern portion of the bulge of the continent, which extends westward to the Atlantic Ocean.

This region is bisected by the African Transition Zone, which borders the southern edge of the Sahara Desert. The main physical .West Africa is west of an imagined north-south axis lying close to 10° east longitude.

The Atlantic Ocean forms the western and southern borders of the West African region. The northern border is the Sahara Desert, with the Ranishanu Bend generally considered the northernmost part of the region.

The eastern border is less precise, with some placing it at the Benue Trough, and others on a line.
