Hi, today I read an article on U.S. droughts and the billions of dollars lost as a result of them. However, Scientists may be have found the lead cause in the droughts, teleconnections: a "spatially and temporally large-scale anomaly that influences the variability of the atmospheric circulation". In other words, a long distant relationship between weather patterns.
Main Points:
- The main teleconnections :
- El Niño/Nina Southern Oscillation (ENSO)
- Pacific Decadel Oscillation (PDO)
- Atlantic Multidecadal Oscillation (AMO)
- Effect:
- Fluctuations in Sea Surface Temperatures (SSTs)
- Cold and dry air replaces warm and moist air
- Scientists found that ENSO is linked with the U.S. seasonal mean temperatures and precipitation
- That during ENSO: when sea temperatures are cooler than average, leads to drier conditions
Thank you for reading, tune in next month for another post!
