This will be interesting to monitor… For [...]

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 [...]

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 [...]

In the article “Ubiquity of Biological Ice Nucleators in Snowfall” Christner et al., it is made clear how important biological particles are as ice nucleators and how many of these particles are bacteria. One thing that I found interesting is how high of a temperature bacteria can act as an ice nucleator, -2C. It is [...]
