Statistical Quality Control Algorithm for In Situ Sea Surface Temperatures
<p>In situ sea surface temperature (SST) observations—collected from drifting buoys, moored systems, and ships—are essential for the calibration and validation of satellite SST products, climate monitoring, and operational oceanography. However, the quality of these observations varies …

Impacts of ENSO on coastal South African sea surface temperatures
… is well documented and provides skill in the seasonal forecast of rainfall but little is known of the impact of ENSO on the ocean surrounding South Africa. The aim of this study is to assess the impact of ENSO on sea surface temperatures around the coast of South Africa and to calculate SST …

Rapid marine cyclogenesis forecast sensitivity to high resolution sea surface temperatures during ERICA IOP-5
The influence of high resolutions sea surface temperatures (SST) on Nested Grid Model (NGM) predictions of rapid marine cyclogenesis is examined. Satellite data provides a gridded SST analysis with a resolution of 50 km. Forecasts using the operational "blended" SST analysis with a neutral …

Sea Surface Temperatures and Vertical Wind Shear as Precursors to Tropical Cyclone Activity in the Caribbean and an Expanding Main Developing Region
<p>Sea surface temperatures and vertical wind shear are essential to tropical cyclone formation. TCs need warm SSTs and low shear for genesis. Increasing SSTs and VWS changes influence storm development. This work analyzes SST and VWS trends for the Caribbean, surrounding region, and the Atlantic …

A comparative study of Phoebetria albatrosses' interactions with mesoscale oceanographic features south of the African continent
… in relation to environmental parameters such as sea surface temperature. Interaction with mesoscale features expressed by sea surface temperatures, was tested with statistical models. Tracked P. fusca demonstrated positive association with sea surface temperatures in the Southern Indian Ocean, in …

Mesoscale convective complexes over southern Africa
… position, regional orography and local sea surface temperatures, ensures that subtropical southern Africa experiences considerable spatial and temporal variability in rainfall and is prone to both frequent flooding and drought events.

The influence of the Agulhas Current on two South African extreme weather events
Surface station, satellite and NCEP re-analysis data are used to examine the evolution of two severe storms that occurred over the eastern coastal regions during South Africa's summer season 1998/99. The storms in November and December were both accompanied by heavy rainfall in two widely separated …

The influence of volcanic stratospheric aerosols on interannual global climate variations
… in wind strength and corresponding increase in sea surface temperatures (SST) in the eastern tropical Pacific Ocean. The observational evidence for an association between the record of volcanic eruptions and SST and the Southern Oscillation Index (SOI, Tahiti SLP minus Darwin SLP) over the last …

The role of atmospheric and oceanic forcing in Greenland outlet glacier behaviour
Satellite-derived sea surface temperature data and surface air temperature records from coastal Greenland weather stations were used to evaluate the respective roles of atmospheric and oceanic forcing on frontal position variations of Helheim, Kangerdlugssuaq Glacier and Jakobshavn Isbrae. At the …

The relationship between ENSO, seasonal rainfall, and circulation patterns in South Africa
… El Niño-Southern Oscillation phenomenon (ENSO), seasonal rainfall, and atmospheric circulation patterns at the 1000 hPa and 500 hPa levels are investigated. Firstly, correlations between early-summer (October to December), late-summer (January to March) rainfall over South Africa, and sea-surface …

A holocene sea surface temperature record in mollusc shells from the South African coast
… the construction of a Holocene history of sea surface temperatures in coastal regions of the southern Benguela and eastern Agulhas Bank of South Africa, using marine mollusc shells preserved in archaeological middens. Two independent palaeothermometers were employed: the traditional oxygen …

Climate and Hydrographic Variability In the Indo-Pacific Warm Pool Over the Past 26,000 Years
… region of the modern ocean, with annual average sea surface temperatures upwards of 28°C. As such, it is the largest single source of heat and moisture to the atmosphere. Climate modeling efforts and paleoceanographic reconstructions have shown that the hydrology of the IPWP responds to …

The South Indian Convergence Zone and relationship with rainfall variability in Mozambique
Southern Hemisphere atmospheric circulation and sea surface temperatures in the South Indian Ocean, associated with the South Indian Convergence Zone (SICZ), the main rain producing system over southern Africa, and links with rainfall over Mozambique, are analysed. Cluster analysis applied to …

Investigation the use of oxygen and carbon isotopes and sclerochronology on Turbo sarmaticus and Donax serra for palaeoenvironment reconstruction at Pinnacle Point, South Africa
… and the bivalve Donax serra to reconstruct sea surface temperatures. These are the species most commonly retrieved from archaeological assemblages of the South Coast of South Africa. The material analysed for this thesis includes modern and archaeological shells from Pinnacle Point, Mossel …

Antarctic sea-ice extent, Southern hemisphere circulation and South African rainfall
… model (OCM) to a reduction in Antarctic sea-ice extent during summer and winter, with emphasis on non-polar and southern African climates. Following an evaluation of the OCM, the control and perturbation simulations are analysed. The controls are forced by prescribed, observed sea surface …

Precipitation variability and change over Morocco and the Mediterranean
… the Mediterranean Basin. In addition to strong seasonality and high inter-annual variability, annual precipitation remains low (<500mm) across much of the region. Furthermore, the situation is not expected to improve under climate change as models project a sustained decline in precipitation in …

Holocene climate and environmental dynamics on the Tristan da Cunha island group, South Atlantic
… sector of Antarctica, which caused expansion of sea ice and northward movement of the westerlies. Several periods with increased catchment erosion and further increased precipitation follow this transition. These periods were probably caused by increased air humidity as a response to higher sea …
