Periodicity of Downward Longwave Radiation at an Equatorial Location
A good understanding of the diverse mechanisms in the atmosphere is required in modelling the climate. In this study, the diurnal and seasonal patterns of all-sky downward longwave radiation (DLR) at Ilorin (8o 32l N, 4o 34l E), Nigeria were investigated alongside relative humidity (RH) and temperature. The average diurnal pattern of DLR gives an arc that begins by increasing gradually with som...

متن کاملStellar Fluxes as Probes of Convection in Stellar Atmospheres
Convection and turbulence in stellar atmospheres have a significant effect on the emergent flux from late-type stars. The theoretical advancements in convection modelling over recent years have proved challenging for the observers to obtain measurements with sufficient precision and accuracy to allow discrimination between the various predictions. An overview of the current observational techni...
متن کاملA simple expression for vertical convective fluxes in planetary atmospheres
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 ...
متن کاملRelationships between outgoing longwave radiation and diabatic heating in reanalyses
to upper troposphere. The compensating effects in LW and SW radiation are largely linked to variations in cloud fraction and water content (vapor, liquid and ice). These radiative balances in reanalyses are in agreement with idealized calculations using a column radiative transfer model. The overall relationships between OLR and diabatic heating are robust among the different reanalyses, althou...
