长江流域旱涝与太平洋OLR场的关联

The relationship between drought/flood over the Chagjiang River Basins and outgoing longwave radiation

This paper presents with some results from analyses which show that the arrays of the OLR anomaly pattern might enter the opposite appearances between the drought and flood cases over the Changjiang River Basins. When the negative (positive) OLR anomaly region appeared over the west tropical Pacific with drought/Hood events, the positive (negative) OLR region might be over the equatorial central Pacific. And the most significant difference occured over the equatoral central Paific.The multi-spectral analysis shows that the processes of OLR over the equacoral central Pacific affected on the drought/flood over the Changji-ang River Basins seem to be the westerly propagations.
