[MSD46-P03] Variation of Phase Relation Between OLR in Western Pacific Warm Pool and the Equator
Keywords:OLR, WPWP, teleconnection
Motivation of this study is that clarifying the phase relation of about one-month periodic variation of OLR in Western Pacific Warm Pool and the equator. We have performed cross correlation analysis between OLR in Western Pacific Warm Pool and the equator by using interpolated OLR data from NOAA. Western Pacific Warm Pool is known as correlating negatively with lightning around Marine Continent and typhoon-rich area. The equator is known as correlating positively with lightning around Marine Continent and typhoon-pool area. We will discuss about characteristics of variation of phase relation from 1974 to 2018 which includes 21st to 24th of solar cycle.
