Researchers at Penn State found a correlation between jet stream strength and precipitation in the Sahel region, which has been experiencing drought since the 1970s. The Tropical Easterly Jet was mostly weaker during dry periods, while the African Easterly Jet showed slightly stronger patterns in very dry years.
Researchers can now forecast long-term climate cycles, such as the El Niño Southern Oscillation and Pacific Decadal Oscillation. By understanding these cycles, policymakers can develop strategies to lessen climate-related effects, potentially ensuring cultural survival.
A computer model predicts reliably the severity and timing of drought episodes six months in advance, helping farmers choose drought-tolerant crops and minimizing economic losses. The researchers also highlight the need to maintain adequate river levels to prevent barge traffic disruptions and ensure water supply.
Researchers from College of William and Mary and University of Arkansas found that extreme droughts from 1587-1589 and 1606-1612 affected the Tidewater region, decimating corn crops and aggravating relations with Native Americans. The findings suggest that even well-planned colonies would have struggled under these climatic conditions.
Studies found that tree species' moisture preference doesn't always correlate with their growth rate during droughts. Researchers used tree rings to analyze the energy stored in trunks, revealing inconsistencies between leaf physiology and radial growth.
