Trends in rainfall indices for six Australian regions: 1910-2005
Understanding rainfall variability, shifts and trends is of primary importance when considering the potential for biophysical, social and economic impacts. An increase in mean rainfall could enhance agricultural production and water supply. However, if this increase is associated with more extreme rainfall events, it can enhance flood frequency and intensity. Conversely, decreases in mean rainf...
متن کاملmultivariate analysis of relationship between seasonal rainfall in iran with climate indices
in this article the relationship between the amount of seasonal rainfall (autumn, winter and spring) and climate indices in iran have been studied. the climate indices (the southern oscillation(soi),the north atlantic oscillation(nao), arctic oscillation(ao),nino 3/4,the multivariate enso index(mei),trans_ nino index(tni) and the pacific decadal oscillation(pdo) are used as independent variable...
متن کاملRegional Rainfall Forecasting using Large Scale Climate Teleconnections and Artificial Intelligence Techniques
This paper presents an Artificial Intelligence approach for regional rainfall forecasting for Orissa state, India on monthly and seasonal time scales. The possible relation between regional rainfall over Orissa and the large scale climate indices like El-Niño Southern Oscillation (ENSO), EQUitorial INdian Ocean Oscillation (EQUINOO) and a local climate index of Ocean-Land Temperature Contrast (...
متن کاملA Multivariate Artificial Neural Network Approach for Rainfall Forecasting: Case Study of Victoria, Australia
El Nino southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) have enormous effects on the precipitations around the world. Australian rainfall is also affected by these key modes of complex climate variables. Many studies have tried to establish the relationships of these large-scale climate indices among the rainfalls of different parts of Australia, particularly Western Australia, New So...
متن کاملClimate indices, rainfall onset and retreat, and malaria in Nigeria.
BACKGROUND & OBJECTIVES Rainfall in western sub-Saharan Africa is related to seasonal shifts of the Inter-tropical Convergence Zone, which moves northward early in the year, retreating in the second half of the year. The objective of the present study was to determine significant relationships between onset and retreat timing and climate indices. The relationship between timing and malaria case...
