2012 IndyCar Series
The 2012 IZOD IndyCar Series was the 17th season of the IndyCar Series, and the 101st season of American open wheel racing. Its premier event was the 96th Indianapolis 500, held on Sunday, May 27. The series was sanctioned by IndyCar, and took place in three countries on two continents. Chevrolet returned to the series for the first time since 2005 while Lotus debuted, with the latter leaving the IndyCar Series after the 2012 season due to poor performance.
Indian Ocean Dipole
The IOD also affects the strength of monsoons over the Indian subcontinent. A significant positive IOD occurred in 1997–98, with another in 2006. The IOD is one aspect of the general cycle of global climate, interacting with similar phenomena like the El Niño-Southern Oscillation (ENSO) in the Pacific Ocean.
