Rainfall anomalies over southern China are found to be asymmetricly influenced by the Indian Ocean Dipole (IOD), with a far stronger influence from positive IOD (pIOD) events. A greater convection anomaly and an equivalent-barotropic Rossby wave train response occurs during pIOD events than during negative IOD (nIOD) events. Over the Bay of Bengal (BOB) and South China Sea (SCS), an associated ...

qorveh – dehgolan aquifer is one of the ground water resources in kurdistan. increase in pumping of water has dropped water table level significantly. this study considers the relationship of fluctuations in precipitation, humidity and evaporation with ground water table level. after preparing the base map and the rainfall data accuracy, isohyetal map of basin was drown. based on isohyetal ma...

Variation and shift in the seasonal pattern of the hydro-climatic factors is probably because of climate related changes. Rainfall, river inflow, snowmelt, and consequent fluctuation in water level are the hydro-climatic factors that influence the inland fisheries production worldwide. Increase in rainfall and water level favours the reproduction, recruitment and immigration of fish in the inla...

the projected rainfall change under various scenarios is likely to have both positive and negative implications on agriculture and water supply because in rainfall pattern across the country. rise in rainfall is seen over all states except punjab, rajasthan and tamil nadu, which show slight decrease in precipitation in the future scenarios. marked increase in covering the western ghats and nort...

A single-station technique is used to compute vertical velocities over San Juan, P. R., at standard constant pressure levels from 850 to 100 mb. Periods of strong upward motion are observed to occur rather frequently within the layer 400 to 100 mb. and these are discussed in relation to subsequent precipitation patterns.

This algorithm was originally developed for application to the SSM/I instrument for the Global Precipitation Climatology Project (GPCP) (Wilheit et al., 1991) The lowest frequency of the SSM/I was 19.35 GHz so that many heavy rain events could not be measured due to saturation. The use of the form of the rain PDF allowed us to fill in the contribution from these heavy rain rates by extrapolatio...

The diurnal variations in surface winds, rain, and clouds over Taiwan are presented for three rainfall regimes: the mei-yu (16 May–15 June), summer (16 July–31 August), and autumn (16 September–15 October). Though the magnitude of diurnal island divergence and convergence is similar under each regime, the diurnal variations of rain and clouds vary considerably between the regimes. These differe...

Currently, it is a hot research topic to retrieve the wave parameters by using X-band marine radar. However, rainfall noise usually exists in collected radar images, which seriously interferes with extraction of parameters. To reduce influence noise, zero-pixel percentage (ZPP) method widely used detect but detection accuracy limited, and selection threshold needs be further studied. Based on Z...

Rainfall data at fine resolution and knowledge of its characteristics plays a major role in the efficient design and operation of agricultural, telecommunication, runoff and erosion control as well as water quality control systems. The paper is aimed to study the statistical distribution of hourly rainfall depth for 12 representative stations spread across Peninsular Malaysia. Hourly rainfall d...
