We explore the vertical convective flux Fc in a radiative-convective grey atmosphere. An expression of the form Fc = Fsτo/(C +Dτo) appears useful, where Fs is the shortwave flux absorbed at the base of an atmosphere with longwave optical depth τo and C and D are constants. We find excellent agreement with an idealized grey radiative-convective model with no shortwave absorption for D = 1 and C ...

The first step was to collect, process, and examine the data from SHEBA. The meteorological data include wind speed, air temperature, and longwave and shortwave radiation. Ice core data were used to calculate an average profile of ice salinity and porosity. Snow cover variations were combined into bins to produce a time history of the fractional coverage of snow as a function of time. Ice stres...

The recent paper by Heymsfield et al. (2006, hereafter H06) comments on the accuracy of various in situ measurements of the extinction coefficient by in situ cloud probes. The measurements have particular relevance for their contribution to understanding cloudradiative properties. Climate models are largely concerned with predicting fields of electromagnetic radiation. However, they instead tra...

Abstract – Time-series of global outgoing radiation fields have been reconstructed for the last 20 years using satellite observations from various space systems including some Russian systems. It was detected that during the past two decades global outgoing longwave radiation (OLR) increased (considerably...

Global information of cloud ice water path (IWP) is urgently needed for testing of global climate models (GCMs) and other applications. Accurate quantification of the IWP is essential for characterizing the hydrological and radiation budget. For example, the reflection of shortwave radiation by ice clouds reduces the solar energy reaching the earth’s surface. Ice clouds can also trap the longwa...

This article focuses on the short-term prediction algorithm for ice condensation highway pavement. Solar radiation, ground long wave and atmospheric inverse radiation are main factors affecting road surface temperature changes. According to principle of heat transfer, there is a balance relationship among these three factors. Therefore, based between radiations physical formula, this designs ic...
