Evidence suggests the jet stream was at least partly responsible for the widespread drought conditions during the 1930s Dust Bowl in the Midwest United States. Normally, the jet stream flows east over the Gulf of Mexico and turns northward pulling up moisture and dumping rain onto the Great Plains. During the Dust Bowl, the jet stream weakened ...
They noted that one of the most El Niño events since 1950 - a climate pattern that causes the Pacific jet stream to shift south and east, leading to warmer and drier conditions in the northern US ...
During the El Niño portion of ENSO, increased precipitation falls along the Gulf Coast and Southeast due to a stronger than normal, and more southerly, subtropical jet stream. [8] In the late winter and spring during El Niño events, drier than average conditions can be expected in Hawaii. [9]
This is due to the behavior of the jet stream — essentially a river of air that storms flow through — which often shifts north during a La Niña winter. ... drought conditions could worsen ...

legend Temperature anomaly in Northern Europe in July 2018 The 2018 European drought and heat wave was a period of unusually hot weather that led to record-breaking temperatures and wildfires in many parts of Europe during the spring and summer of 2018. It is part of a larger heat wave affecting the northern hemisphere, caused in part by the jet stream being weaker than usual, allowing hot ...
In parts of East Africa, there were five failed rainy seasons in a row between 2020 and 2022, as the region suffered its worst drought for 40 years. This displaced 1.2 million people in Somalia alone.
Diagram showing ingredients needed for severe weather. The red arrow shows the position of the low level jet stream, while the blue arrow shows the location of the upper-level jet stream. Severe thunderstorms can be assessed in three different categories. These are "approaching severe", "severe", and "significantly severe".
