In the article “Midweek increase in U.S. summer rain and storm heights suggests air pollution invigorates rainstorms” printed in the Journal of Geophysical Research, Bell et al. make a strong case that air pollution plays a role in changing both precipitation coverage and intensity during summer afternoon thunderstorms. Pollution aerosols act to delay precipitation in [...]

Effects of Absorbing Aerosols on Cloud Absorption and Forcing

March 25th, 2008 · No Comments

It would be assumed that in the exploration of the albedo and forcing ratios of pure clouds, one would attain values equal to 1.0. This being the case, how would an observer go about explaining an albedo ranging from .7 to .8 or a cloud forcing ratio consisting of 1.5? These two aberrations have been [...]

One thing that I found interesting is how high of a temperature bacteria can act as an ice nucleator, -2C. It is [...]
