Sea level and climate variability at Zanzibar
… level at Zanzibar, and the relation of these to climate variability over the tropical western Indian Ocean during the 1997-1998 EI Niño and the 2000-2001 la Niña periods. The sea level data used in this study has been collected over a period of nine years from 1996 to 2004. Analyses have shown …

Climate variability and glacial dynamics in the Himalaya
In den Hochgebirgen Asiens bedecken Gletscher eine Fläche von ungefähr 115,000 km² und ergeben damit, neben Grönland und der Antarktis, eine der größten Eisakkumulationen der Erde. Die Sensibilität der Gletscher gegenüber Klimaschwankungen macht sie zu wertvollen paläoklimatischen Archiven in …

Reconstructing Tropical Pacific Climate Variability from Coral Archives
… Pacific Ocean is a critical component of the climate system, and its mean state and variability are linked to effects across the globe. Our understanding of the area is limited by the scarcity of direct observations of important climatic variables prior to the mid-twentieth century, without …

The Role of Climate Variability in Duck Population Ecology
Climate change is having profound impacts on animal populations globally, and is expected to become a stronger stressor in future, influencing abundance and persistence of many species. In northern hemisphere bird populations, local weather and climate cycles play important roles via effects on …

Studies of climate variability in a simple coupled model
The mechanisms of variability of a coupled atmosphere-ocean model are investigated through the study of two coupled configurations: an aquaplanet in which gyres are absent, and an aquaplanet in which a ridge extending from pole to pole supports gyres. Empirical Orthogonal Functions (EOFs) are used …

Mechanisms and prediction of climate variability in tropical North Africa
… Superimposed on this basic state, large-scale variability dictates the life of the people and their socio-economic activities. The tropical North Africa climate exhibits a spectra! energy mainly in the ENSO and decadal temporal band as revealed by wavelet transform. The lowland Sahelian climate …

Patterns of climate variability of the Northern Hemisphere wintertime circulation
The principal patterns of variability of the extratropical Northern Hemisphere (NH) wintertime circulation are examined. The two-dimensional phase space defined by the two leading PCs of the monthly-mean sea-level pressure (SLP) field poleward of 20°N is used as a basis for surveying the structure …

Climate Variability Influences Women’s Attitudes Towards Intimate Partner Violence (IPV)
… against women. Our study examines the effects of climate conditions on women’s attitudes towards wife beating. The demographic health surveys (DHS) dataset includes over 550,000 women in 38 countries, asked a series of wife beating justification questions in the domestic violence module. Using a …

High-Latitude Southern Hemisphere Climate Variability, Trends, and Tropical Forcing.
… investigates several inter-related aspects of climate variability in the Southern Hemisphere (SH) high-latitudes, with a focus on the time-varying behaviour and long-term trends in Antarctic sea ice and atmospheric circulation, as diagnosed from observations, reanalyses, and simulations using …

Impact of climate variability and human activities on water resources.
… the extent to which the global driving forces (climate change, groundwater dynamics, etc.) and human activities (land-use/land-cover changes, dam construction, etc.) interact and affect the hydrological regime in some selected basins in the semi-arid region of southeastern Spain. To conduct a …

Evaluating effects of climate variability on postharvest quality of strawberries
… was to evaluate the effects of environmental variability on several characteristics of strawberry postharvest quality. Acids, sugars, colour, firmness, anthocyanins, visual evaluation for detection of bruises and mould development were assessed. Work at the initial stages revealed a positive …

Climate variability and drought in the South Platte River Basin
… of drought. This study used multiple sources of climate and water consumption data to better understand climate and water consumption changes during drought: North American regional Reanalyses (NARR), Global Land Data Assimilation System (GLDAS), United States Geological Survey (USGS), and …

Influence of Climate Variability on Terrestrial Hydrology in North America
To study the impacts of climate variations on the terrestrial hydrologic processes, ERA-15 dataset (1979--1993) is used to drive LABs for all basins over North America. The anomalies of the model forcing and output are correlated with climate anomalies, such as ENSO, NAO and PNA. It is found that …

The role of ocean dynamics within tropical Atlantic climate variability
… in the tropical Pacific, tropical Atlantic variability is viewed from an energetics perspective and contrasted against the Pacific at both seasonal and inter-annual timescales. The character of remotely forced thermocline depth variability is evaluated using available potential energy which …

Tropical climate variability from the last glacial maximum to the present
… evaluates the nature and magnitude of tropical climate variability from the Last Glacial Maximum to the present. The temporal variability of two specific tropical climate phenomena is examined. The first is the position of the Intertropical Convergence Zone (ITCZ) in the Atlantic basin, which …

On the external forcing of Indian Ocean climate variability across timescales
… to understand the dynamics of external climate forcings and the nature of the climate system’s responses for improved predictability. These forcings include low-probability, high-impact events like explosive volcanic eruptions as well as the continued injection of anthropogenic …
