Developments in three-d cloud radiation during the last few a long time are assessed and distilled into this contributed quantity. Chapters are authored by way of subject-matter specialists who address a wide viewers of graduate scholars, researchers, and someone drawn to cloud-radiation methods within the sun and infrared spectral regions. After introductory chapters and a bit at the basic physics and computational concepts, the amount widely treats major software parts: the effect of clouds at the Earth's radiation funds, that's a vital point of weather modeling; and distant statement of clouds, specifically with the complicated sensors on present and destiny satellite tv for pc missions.

Sample text

I highly recommend Chap. 4 for a remarkably balanced introduction to both types of numerical radiative transfer methods and the strengths and weaknesses of each. 25 It was a feat just to calculate 20,000 trajectories, far fewer than were needed to beat errors down below 10% except by extensive spatial and/or angular averaging. It was impossible to calculate enough realizations to do proper ensemble-averages. Random number generators, the heart of every Monte Carlo model, were suspect and sometimes wrong.

This time, however, his distributions had no small drops! ” And as far as radiation people were concerned, drop distributions remained either cloud drops below 15–20 microns, or rain drops above a few hundred microns. Drizzle drops in the 100 micron range fell between the cracks – until millimeter-wave cloud radars were invented and drizzle began, when present, to dominate their reflectivities. I call all the analytic distributions invented by radiation people, with their arbitrary cutoffs, “fantasy drop distributions” because their inventors didn’t care what the real functional form was22 and they never bothered to analyze boatloads of cloud aircraft data to learn the truth.

J. Wiscombe Fig. 8. Past estrangement between cloud and rain scientists is mirrored in the assumptions they make about drop size distributions. On the left is a typical radiation size distribution of the 1980s, falling off exponentially with no possibility of larger drops, much less rain. On the right are several traditional raindrop size distributions along with a distribution (WWH = Wiscombe/Welch/Hall) taken from a rising-parcel cloud model; these distributions are typically truncated with no extension to smaller sizes.
