Changes in indices of climate extremes are studied on the basis daily series temperature and precipitation observations from 116 meteorological stations central south Asia. Averaged over all stations, indicate warming both cold tail warm distributions minimum maximum between 1961 2000. For precipitation, most regional wet show little change this period as a result low spatial trend coherence with mixed positive negative station trends. Relative to changes total amounts, there is slight...
Abstract Agriculture (arguably the backbone of India's economy) is highly dependent on spatial and temporal distribution monsoon rainfall. This paper presents an analysis crop–climate relationships for India, using historic production statistics major crops (rice, wheat, sorghum, groundnut sugarcane) aggregate food grain, cereal, pulses oilseed production. Correlation provides indication influence rainfall some its potential predictors (Pacific Indian Ocean sea‐surface temperatures, Darwin...
ABSTRACT Temporal changes in the extreme rainfall and temperature characteristics of major river basins on a daily time scale are examined using high‐resolution gridded (1951–2014) (1951–2013) data sets. Trend analysis is carried out to examine temporal frequency, area covered intensity events. Rainfall 10 cm during southwest monsoon season ( JJAS ), maximum 40 °C summer MAM ) minimum winter DJF have been used as thresholds define weather events these basins. Analysis indicates that zero...
Abstract Hourly rainfall data recorded at 72 Self Recording Raingauge Stations (SRRG) for the period 1969–2006 are utilized to study characteristic features of hourly and diurnal variations in India. Temporal changes short duration (less than 12 h) extremes examined. Time distribution a heavy rain spell 24 h duration, which is an important component water resources management flood control studies, analysed. Different aspects such as, average number hours year, empirical probability...
ABSTRACT Changes in the amplitude and phase of diurnal cycle rainfall due to changes background circulation thermodynamics associated with intraseasonal variability Indian summer monsoon have important implications for weather prediction over region. Hourly data available at 91 stations 30 years observations are examined determine role variations modulating four homogenous regions. Harmonic analysis shows predominance principal harmonic during break monsoon. During an active first two...
Industrialization and urbanization are the most dominant causal factors for long-term changes in surface air temperatures. To examine this fact, long term surface-air temperatures have been evaluated by linear trend different periods, i.e. 1901-2013, 1901-1970 recent period 1971-2013 as rapid industrialization was observed during four decades. In present study, seasonal annual mean, maximum minimum temperature data of 36 stations 1901-2013 used. These classified into 4 groups, namely major,...
Probable Maximum Precipitation (PMP) is the greatest depth of precipitation for a given duration meteorologically possible design watershed or storm area. It can be thought as reasonable upper limit rainfall that could anticipated in region. PMP values have been estimated 173 monitoring stations Maharashtra, using 113 years long period daily data applying Modified Hershfield technique. Station captures extreme behavior better way compared to gridded sets it represents normalized versions....
A short‐duration heavy rainfall events over India have been studied using hourly data of 126 stations for the period 1969–2015 Indian summer monsoon season. The classified into two categories. first category pertains to cloud burst (CB). CB further types, viz. “CBa” and “CBb.” CBa are associated with in steep slope mountainous regions Himalayas identified based on flash floods damages properties human losses, irrespective amount. CBb >10 cm/hr as per definition by Meteorological...
Abstract Spatio‐temporal variability of contributions stratiform and convective rainfall to Indian monsoon (June–September) have been investigated using hourly data well distributed 126 stations in India for the period 1969–2015. The criteria used identifying are ≤5 mm spatial homogeneity. study showed that exhibits two distinctive features, viz. component dominating over peninsular (southern) northern India. diurnal variation shows domination activity afternoon hours parts Intra‐seasonal is...
The long-term impacts of climate change on water resources are expected to be considerable in many parts the globe.Resulting hydrologic changes can have a high impact river basins like Krishna, India and Murray Darling, Australia where severe competition between stakeholders states exists.Australia is already experiencing significant change: average surface air temperatures increased by 0.9°C since 1950 precipitation has declined along east west coasts country.Analysis emission scenarios...
Abstract North–South‐oriented mountains (known as “The Western Ghats [WG]”) running parallel to the west coast of peninsular India separate Maharashtra state (lying on northwest India) into two meteorological subdivisions (a) Konkan lying windward side WG receiving high monsoon rainfall (2,390 mm) and (b) Madhya (MM) leeward low (579 mm). The has more WG, viz. Marathwada Vidarbha, which however do not lie immediate WG. In this study, a subdivision MM is further subdivided north–south strip...
