Spatial and Temporal Characteristics of Outgoing Longwave Radiation (olr): an Update
A study of the Outgoing longwave radiation (OLR) values (Unit, W/m2) observed by various satellites during 1979-2002 revealed that the OLR values varied considerably from one geographical region to another (∼100-300 units). The climatology was latitude dependent. At middle and high latitudes, the range (minimum to maximum) was∼40-60 units, with maximum in local summer and minimum in local winte...
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 ...
متن کاملThe Walker circulation, diabatic heating, and outgoing longwave radiation
For the tropical atmosphere on planetary scales, it is common to model the circulation using strong damping. Here, with new data analysis techniques, evidence suggests that damping can actually be neglected. Specifically, near the equator, the east–west overturning circulation is in agreement with the undamped wave response to atmospheric heating. To estimate the heating, satellite observations...
متن کاملAnomalous Global Redistribution of the Earth Radiation Budget Components
* Corresponding author. ** The work has been partly supported by RFBR grant 04-01-00397-а. 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...
