| 内容記述 | Tamil Nadu state, located in the southeastern part of Peninsular India receives most of its rainfall during October through December which is referred to as Northeast monsoon rainfall (NEMR). The onset and distribution of NEMR plays a crucial role on both agriculture and economy of the Tamil Nadu State of Indian subcontinent. It is interesting to note that Tamil Nadu Southwest monsoon rainfall (SWMR) received between June and September months has positive correlation with SOI, while NEMR shows negative correlation with SOI. A study was undertaken to investigate the relationship between global tele-connection signals viz. El-Nino- Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD), and precipitation over Tamil Nadu during the northeast monsoon season. The results indicated that NEMR of Tamil Nadu had the highest positive correlation with Nino-3 SST for the month of July indicating that whenever there is a rise in sea surface temperature in Nino-3 region, there is an increase in NEMR and vice-versa. The results also indicated that under extreme negative July SOI condition Tamil Nadu received 17.7 % more than the normal NEMR and that of the extreme positive condition 17.9 % less than the normal NEMR. To understand the relationship and/or local dynamic structure, composites of circulation field for the extreme El Nino/La Nina years are compared with the mean state. Composite circulation analysis clearly showed that in extreme El Nino years (SOI < -10) Bay of Bengal has a positive sea level pressure (SLP) anomaly and Arabian sea has a negative SLP anomaly, which resulted in strong northeasterly wind to the southern part of India. The strengthened Northeast monsoon brings more moisture and precipitation to the Tamil Nadu region in the El Nino years. The opposite case is also true. A strong negative anomaly is observed in the Bay of Bengal during the La Nina years (SOI > 10), which resulted in weak NE monsoon. | |||||
