A climatologist compares rainfall data: region A received 1020 mm in a year, up 15% from the 10-year average. Region B received 10% less than region A’s previous year’s rainfall of 1100 mm. What was region B’s rainfall that year?

Climatologist Compares Rainfall Data: How Region A’s Record Rainfall Contrasts with Region B’s Decline In recent climate analysis, a climatologist has drawn attention to striking rainfall patterns across two regions—Region A and Region B—highlighting a significant 15% increase in Region A’s annual rainfall compared to its long-term average, contrasted with a 10% drop in Region B from its 2022 peak. Understanding these trends not only reveals shifting weather patterns but also underscores the regional climate divergence shaped by changing climatic conditions. According to the latest data, Region A recorded 1,020 mm of rainfall this year—15% above its average annual rainfall over the past decade. This surge reflects intensified precipitation, likely linked to altered atmospheric circulation and warmer ocean temperatures influencing storm frequency and intensity. In stark contrast, Region B’s rainfall declined by 10% from its previous year—specifically from 1,100 mm an in the prior year—bringing its total to 990 mm for the affected year. This drop suggests a drier trend, possibly tied to shifts in regional weather systems or broader climate phenomena such as drought persistence or reduced monsoon activity.
