Effects of Diurnal Variations of Outgoing Longwave Radiation Over the Tropical Oceans
Several current problems in atmospheric radiation over the tropical oceans may have at least partial solutions as effects of diurnal variations of outgoing longwave radiation (OLR). At issue are explanations for the following: a) excessively large amplitudes (in relation to theory) of the diurnal thermal tides over the tropical oceans (Braswell and Lindzen 1998); b) reported observations of exc...
متن کاملENSO surface longwave radiation forcing over the tropical Pacific
We have studied the spatial and temporal variation of the surface longwave radiation (downwelling and net) over a 21-year period in the tropical and subtropical Pacific Ocean (40 S–40 N, 90 E-75 W). The fluxes were computed using a deterministic model for atmospheric radiation transfer, along with satellite data from the ISCCP-D2 database and reanalysis data from NCEP/NCAR (acronyms explained i...
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...

متن کاملStudy of outgoing longwave radiation anomalies associated with Haiti earthquake
The paper presents an analysis by using the methods of Eddy field calculation mean and wavelet maxima to detect seismic anomalies within the outgoing longwave radiation (OLR) data based on time and space. The distinguishing feature of the method of Eddy field calculation mean is that we can calculate “the total sum of the difference value” of “the measured value” between adjacent points, which ...
