Climate is one of the major reasons that made Bihar a major agricultural hub, which might had made people inhabit this region in ancient times. These include annual mean temperature, rainfall, potential evapotranspiration and reference crop evapotranspiration for the 37 districts of Bihar, which is … However, a general increase in rainfall was not found in recent years.
Analysis of summer monsoon (June to September) rainfall series of 29 subdivisions based on a fixed number of raingauges (306 16 October 2020, 15:19 BST 1 min read. To study the temporal trend of ETo along with its regionwise spatial variation, 32 years (1971-2002) monthly meteorological data were collected for 133 selected stations evenly distributed over different agro-ecological regions (AERs) of India.
Climate Change in Bihar, India -A Case Study. Besides, less variability of annual, Be prepared with the most accurate 10-day forecast for Bihar, Bihar with highs, lows, chance of precipitation from The Weather Channel and Weather.com The increasing atmospheric concentration of carbon dioxide (CO2) and other greenhouse gases is expected to increase precipitation and evaporation proportionally. 16 October 2020, 15:19 BST The interannual variability (range) varies over different sub-divisions, the lowest being 55 and the highest As a result of the CAT Plan, the region has seen improvements to: This case study was developed as part of the India States Climate Leadership Project of the Under2 Coalition. Rangpur is 109 miles from Purnia, so the actual climate in Purnia can vary a bit.
tests show that the rainfall series of 29 sub-divisions are homogeneous, Gaussian-distributed and do not contain any persistence.
The same analysis was also performed on governing meteorological variables to identify the cause of existence of such trend in ETo.
Statistically significant increasing trends in extremes of rainfall are identified over many parts of India, consistent with the indications from climate change models and the hypothesis that the hydrological cycle will intensify as the planet warms.
These ETo values were then analyzed by a nonparametric Mann-Kendall (MK) test (with modified effective sample size approach for serially correlated data) and Sen slope to determine the existence and magnitude of any statistically significant trend over the time period considered in this study. respectively. The reservoir and subsequent submergence zone became functional in 2014-15. However, in the present paper, the modified method of soil and land Irrigability classification as proposed by Palaskar and Varade (1985) and originally suggested Rege et.
Evapotranspiration (ET) is likely to be greatly affected by global warming because of the dependence of ET on surface temperature. Bihar's weather can be divided into four segments: summer, winter, monsoon and post monsoon. The CAT Plan will cover 51,657 hectares which is 97% of prime forest land, thereby benefitting both local villages and wildlife population. Bihar faced major floods in the year 2007, 2008, 2011, 2013, 2016 and 2017 causing loss of life and property, damage to crops, roads and other infrastructure, Modi said. The maximum degree of satisfaction for the compromised solution was 0.64 with 50% groundwater and 50% canal water using fuzzy tool available in MATLAB software. 231% of the normal rainfall, for south Assam and Saurashtra and Kutch sub-divisions respectively. Krishnamurthy CKB, Lall U, Kwon HH.
The highest and the lowest normal rainfall of 284 and 26 cm are observed over coastal Karnataka and west Rajasthan sub-divisions A significant decreasing trend was found in ETo all over India during the study period, which was mainly caused by a significant increase in the relative humidity and a consistent significant decrease in the wind speed throughout the country. ETo was estimated by the globally accepted Food and Agriculture Organization (FAO) Penman Monteith (PM) method (FAO-56 PM). Annual Weather Averages in Rangpur. Predominantly increasing trends in the intensity of extreme rainfall are observed for both exceedance thresholds. It is bounded by Nepal in the north and by Jharkhand in the south. For this study, five different locations were selected for soil irrigability classification and land capability classification in the command of the above distributary. In India, earlier works showed that there was a significant increasing temporal trend in surface temperature and a decreasing trend in grass reference ET (ETo). into land capability classes as per IS 6748 (Part-1) for the purpose of watershed management. considered for the study and constraints like land availability, labour availability, water availability and farmers’ affinity were used. correlation tendency. Statistical The presence of serial and spatial correlation had a significant impact on trend determination. and rapid warming, especially in the last 30 years. ‘X’ limit, was decided based on the land capability class and was found to be 12 to 15 percent in the present case. These locations were at Saraiya, Keshopur, Bhimpur, Dharampur and Bishunpur villages respectively.
Located in the eastern part of India, Bihar is a state with rich cultural heritage and is one of the oldest inhabited places in the world. significant. Because of its geographical location, its climate is greatly influenced by the Himalayas and Ganga plateau.
