Hydrology research, explained
8 open-access hydrology studies, each with a flashcard deck and a quiz.
- South Pacific SSTs, not India, built Brazil’s 2014 drought
Isca experiments show 2013/14 South Pacific and South Atlantic SST anomalies favored the blocking high that dried SE Brazil; Indian Ocean SSTs did not.
- Wet- and dry-climate landslides both speed up in wet years
Across California’s huge rainfall gradient, slow landslides still accelerate when local water years are wetter than average.
- Blue intensity improves Fennoscandian drought records
Delta blue intensity from Swedish drought-sensitive pines explains ~56% of May–July precipitation versus ~37% for ring width.
- 350,000 years of Great Basin groundwater recharge
Devils Hole water-table history plus a groundwater model shows glacial recharge more than doubled modern rates while interglacial drying cut them only modestly.
- Arabian Sea cyclones briefly refill desert aquifers
A few intense tropical cyclones now supply most of interior Oman’s rain and can add cubic kilometres of groundwater, interrupting chronic depletion.
- Nile flood peaks may jump this century
A basin-wide hydrology model driven by 30 CMIP6 climates projects much larger 50- and 200-year Nile floods at Dongola by 2100.
- North Atlantic SSTs lead UK summer droughts
A North Atlantic freshwater–SST pathway leads UK summer rainfall and streamflow droughts by about 1.5 years.
- Prairie wetlands set the pace of annual runoff
In 69% of 109 Prairie Pothole catchments, maximum wetland inundation outpredicts climate for annual runoff, often with a storage threshold.
