El Niño storm tracks
THANKS for this article. As a forecaster who spent 4 decades tracking the dreaded rain-snow line along I-95, DC,PHL and NYC your maps show the wide ranges of El Niño conditions, from very quite 4am-shift cross-country ski trip to work down NYC's 5th Ave, to two-hands-on blown-out umbrellas with raging rain.
While in the West the effect of El Nino's change in the subtropical storm track steers Pacific moisture further south. In the East the GALE Experiment Design Panel, chaired by my former UW Prof. Peter Hobbs, of the mid-1980s investigated the many factors of East Coast snow storm development. https://doi.org/10.1175/1520-The wide range of meteorological and oceanographic phenomena are numerous, including: 1. cyclogenesis, 2. rainbands, 3. cold fronts, 4. coastal fronts, 5. cold-air damming, 6. jet streaks, 6. tropopause folding, 7. low-level jets, 8. cold-air outbreaks, 9. lightning and 10. Gulf Stream.
It is a 4-dimensional Chinese jig-saw puzzle for sure.
