Head in a Cloud

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 [...]

“The operational meteorological community is increasingly realizing the important role of cloud microphysics in the production of heavy precipitation, especially snow(e.g., Roebber et al. 2003)”. This is a direct quote from the journal article “Cloud-Top Temperatures for Precipitating Winter Clouds” by Jay W. Hanna, David M. Schultz, & Antonio R. Irving, of which I [...]

I reviewed the article titled “Aerosol Effects on Clouds, Precipitation, and the Organization of Shallow Cumulus Convection” from the Journal of The Atmospheric Sciences, Volume 65, February 2008. The authors had a desire to study the aerosol effects on clouds and climate. Using large eddy simulations they investigated the effects of aerosol on clouds, precipitation, [...]
