WebFor estimating missing rainfall values, Suhalia et al. [20] and Silva et al. [21] tested multiple methods such as normal ratio, arithmetic mean, inverse distance, aerial precipitation ratio, correlation ratio method, inverse weighting distance and correlation coefficient methods. To compare these methods, they WebSince the normal annual rainfall at stations A and B does not lie within 10% of the normal annual rainfall at station X. So, using normal ratio method, we get P = 250 2 [140 200 + 270 300] = 200 mm If the normal annual rainfall at non-missing station lie within 10% of that at missing station then arithmetic average method can be used.

WebUnderstanding variations in rainfall in tropical regions is important due to its impacts on water resources, health and agriculture. This study assessed the dekadal rainfall patterns and rain days to determine intra-seasonal rainfall variability during the March–May season using the Mann–Kendall ( M K ) trend test and simple linear regression ( S L R ) over the … Web(ii) Normal ratio method Example 2.1 Rain-gauge station D was inoperative for part of a month during which a storm occurred. The storm rainfall recorded in the three surrounding stations A, B and C were 8.5, 6.7 and 9.0 cm, respectively. If the a.a.r for the stations are 75, 84, 70 and 90 cm, respectively, estimate the storm rainfall at station D. ...

WebEstimate the effective rainfall in mm/month if the rainfall is 60 mm/month. From Table 6 it can be seen that the effective rainfall is 26 mm/month. This means that out of 60 mm/month, some 26 mm can be used by the plants; and it is estimated that the remaining (60 - 26 =) 34 mm is lost through deep percolation and run-off.
