Flood Hydroclimatology: Diagnostic Tools For Analysis

"Hydroclimatology places a hydrologic event...in the spatial framework of the regional and global network of changing combinations of meteorologic elements such as precipitation, storm tracks, air masses, and other components of the broad-scale atmospheric circulation"

-from Hirschboeck, K.K. "Flood Hydroclimatology" in "Flood Geomorphology", V.R. Baker, R.C. Kochel, and P.C. Patton (Eds.), John Wiley, NY, p. 27-49.

  • 500 mb global heights map
  • 500 mb N hemisphere anomaly
  • 700 mb global heights map
  • Global jet stream
  • N Hemisphere jet stream
  • Weekly average 700 mb heights
  • Goes 8 hemispheric precipitable water
  • Goes 9 hemispheric precipitable water
