Recent observations from the QuikSCAT and Tropical Rainfall Measuring Mission satellites, as well as a longer record of Special Sensor Microwave Imager winds are used to investigate the existence and dynamics of a Southern Hemisphere partner to the intertropical convergence zone in the tropical Atlantic Ocean. The southern intertropical convergence zone extends eastward from the coast of Brazil in the latitude band 10 8‐38S and is associated with seasonal precipitation exceeding 6 cm month 21…

Tropical Atlantic Variability: Patterns, Mechanisms, and Impacts

This chapter reviews the progress made in the past decade in understanding tropical Atlantic climate variability. In addition to an equatorially anti-symmetric seasonal cycle forced directly by the

SST Indexes in the Tropical South Atlantic for Forecasting Rainy Seasons in Northeast Brazil

May-to-July and February-to-April represent peak rainy seasons in two sub-regions of Northeast Brazil (NEB): Eastern NEB and Northern NEB respectively. In this paper, we identify key oceanic indexes

Influence of Panamanian Wind Jets on the Southeast Intertropical Convergence Zone

Gridded QuikSCAT data has been used to show that a strong confluence zone of the Southeast Pacific Intertropical Convergence Zone (SITCZ) existed in 2000 – 2002 during boreal spring, and the Panama

Seasonal variablity of the heat and mass transport along the western boundary of tropical Atlantic

The Tropical Atlantic comprised between 20oN and 20oS presents today an important key to the knowledge of climatic changes in the world. Two areas are of particular interest: the zonal band of the

Impact of intraseasonal wind bursts on sea surface temperature variability in the far eastern tropical Atlantic Ocean during boreal spring 2005 and 2006: focus on the mid-May 2005 event

Abstract. The impact of boreal spring intraseasonal wind bursts on sea surface temperature variability in the eastern tropical Atlantic Ocean in 2005 and 2006 is investigated using numerical

Shallow Overturning Circulations of the Tropical‐Subtropical Oceans

The Subtropical Cells (STCs) of the Pacific and Atlantic Oceans connect the subtropical subduction regions of both hemispheres to the eastern, equatorial upwelling regimes by equatorward thermocline

The seasonal cycle in the lower troposphere over West Africa from sounding observations

In situ sounding observations from selected sites in West and Central Africa were used to document the seasonal cycle in the lower troposphere associated with the annual migration of precipitation.

The Relationship of Rainfall Variability in Western Equatorial Africa to the Tropical Oceans and Atmospheric Circulation. Part II: The Boreal Autumn

AbstractThis paper examines the mechanisms controlling the year-to-year variability of rainfall over western equatorial Africa during the rainy season of October–December. Five regions with distinct

Seawater temperature changes associated with the North Brazil current dynamics

This study used hydrographic data (CTD and ADCP) collected along the north Brazilian continental shelf and the adjacent oceanic area (the north Brazilian zone) and 13 years of monthly data of sea

Variability of Tropical Diurnal Sea Surface Temperature

Abstract A dataset consisting of daily diurnal warming values from 1996 through 2000 covering the global Tropics (30°N through 30°S) at 0.25° × 0.25° resolution has been created using a

Satellite Observations of the Southeast Pacific Intertropical Convergence Zone

An intertropical convergence zone in the southeast Pacific Ocean is described from monthly mean 1° × 1° ocean vector wind, rainfall, sea surface temperature, and integrated water vapor measurements

Seasonal and interannual variability of atmospheric convergence zones in the tropical Pacific observed with ERS‐1 scatterometer

Monthly images of atmospheric convergence zones in the tropical Pacific were produced with 1992–1994 ERS‐1 scatterometer wind vectors. From the images, the position, width, and intensity of the
