MONITORING OF NORTH AMERICAN SNOW COVER AND ENSO EFFECTS
This study was conducted to monitor the Snow Cover Area (SCA) and to evaluate the effects of El Nino and La Nina on SCA in North America (Excluding Greenland) since 2000/2001 to 2010. The NASA ((National Aeronautics and Space Administration) Earth Observing System Moderate Resolution Imaging …

Teleconnections between seasonal rainfall in coastal Tanzania and Enso
… with the El Nino/Southern oscillation (ENSO), the largest known mode of Southern Hemisphere climatic variation is examined. A rainfall index was formulated from variable Tanzanian coastal stations and used to identify the rainfall characteristics of each ENSO year. Monthly anomalies of …

Impacts of ENSO on coastal South African sea surface temperatures
The impact of El Niño Southern Oscillation (ENSO) on the Southern African inland climate 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 …

The relationship between ENSO, seasonal rainfall, and circulation patterns in South Africa
… the 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 …

Safe Yield for Jointly Operated Reservoir System and Examination of ENSO Impacts
Determination of safe yield of a water source is a basic aspect of water supply planning. In this report, the safe yield is defined as the maximum constant release from a reservoir that is possible during a selected drought period. The yield depends on drought magnitude and duration controlled by …

Understanding the impacts of ENSO patterns on droughts over southern Africa using SPEEDY
The El Niño Southern Oscillation (ENSO) is a major driver of southern Africa droughts, but the nonlinearity of ENSO variation inhibits accurate prediction of droughts. While studies have identified multiple patterns of ENSO, most drought predictions over southern Africa are still based on only two …

Relative Impacts of ENSO and Indian Ocean Dipole/Zonal Mode on Southern African Rainfall
… in relation to El Niño Southern Oscillation (ENSO) and the Indian Ocean Dipole/Zonal Mode (IODZM) for the period 1950 to 1999. An empirical orthogonal function (EOF) analysis of OND rainfall field revealed that the north-south aligned areas of the eastern SADC are located in different …

Understanding the role of stochastic atmospheric forcing in tropical Pacific decadal variability and ENSO modulation
… interacts with the El Niño-Southern Oscillation (ENSO), the dominant mode of interannual climate variability. To answer this question, a suite of climate model experiments is conducted with small time-invariant surface heat flux anomalies associated with the leading atmospheric modes in the …

Evaluating the efficacy of Tridacna derasa and Hippopus hippopus for measuring ENSO signatures in Palau
… for understanding El Niño Southern Oscillation (ENSO), the primary source of interannual climate variability on Earth. In this study, we validate the use of two understudied species of Tridacna, Tridacna derasa and Hippopus hippopus, from Palau to identify ENSO signatures through oxygen isotopic …

The Joint Influence of ENSO and NAO on US Landfalling Hurricanes and their Origination Points
… between the El Niño Southern Oscillation (ENSO) and the North Atlantic Oscillation (NAO). Global atmospheric anomalies were then examined in addition to hurricane landfall and origination locations (i.e., the position hurricane strength is achieved) to see if atmospheric anomalies could …

Analyzing the effects of unforced natural variability and anthropogenic forcing on ENSO variability using CESM
The El Niño-Southern Oscillation (ENSO) is an important contributor to Earth’s inter-annual climate variability, with worldwide weather effects (Whetton and Rutherfurd, 1994; Hoerling and Zhong, 1997; Dai and Wigley, 2000). Understanding how ENSO may change with climate is a major challenge, given …

ENSO forced variations of the sea surface temperature and adjusted sea level along the west coast of the United States
… States during El Nino-Southern Oscillation (ENSO). The strong ENSO years examined were 1957-58, 1972-73, and 1982-83. Moderate ENSO years used were 1966, 1976, and 1987. To look at regional differences in the signals, the time series of daily coastal surface temperature and adjusted sea level …

The Evolution of the El Niño-Southern Oscillation and Tropical Pacific Climate Across the Last Deglaciation
<p>The El Niño – Southern Oscillation (ENSO) is the largest interannual component of Earth’s climate system, capable of exerting significant influence over global climate patterns that affect communities around the globe. Nevertheless, a comprehensive understanding of the ENSO system and its …

An investigation into the relative contributions of ENSO, Benguela Niño and the sub-tropical Indian Ocean dipole on summer rainfall over southern Africa
… the unique impact that SST conditions related to ENSO, Benguela Niño and subtropical Indian Ocean Dipole (SIOD) has on summer rainfall over southern Africa. To achieve this, a partial correlation method was employed to analyse the possible relationship between rainfall variability and interannual …

The Combined Role of ENSO-driven Sea Surface Temperature Variation and Arctic Sea Ice Extent in Defining Climate Conditions in the Southwestern United States
… between El Niño-Southern Oscillation (ENSO) related sea surface temperature (SST) variation and varying Arctic SIC in controlling storm tracks, precipitation patterns, and overall climate conditions in the American southwest. We find that tropical Pacific SSTs greatly influence climate …
