Here I have the Earth Null School site showing total precipitable water in the atmosphere. (watertechbyrie.com)
We also include an estimate from the NCAR LE of the impact of decadal variability in precipitable water in the atmosphere, which can impact GMSL. (pnas.org)
But all were extreme events, both in terms of precipitation rates and of cost, of the sort which we expect to become much more frequent given both theory and observed metrics such as precipitable water in the atmosphere. (realclimate.org)
