Abstract
Tropical Pacific Ocean is an important to study for identifying the influence on Global circulation. El Niño /La Nina even occurs over the tropical Pacific Ocean, with temperatures oscillations. With respect to increase in temperatures, the intensity of El Niño can be divided into strong, moderate and weak. As per the intensity, the year 2009 is a moderate El Niño, but is peculiar due to delay in formation. In this article, TAO/TRITON data is used for analysis between November 2008 and December 2009 to check the variations in the surface and sub-surface temperatures during the manifestation of El Niño. Actually El Niño manifest during December, but during 2009 El Niño it manifested in January. There is a clear evidence in surface and sub-surface temperatures as they are increasing from January 2009, which can explains the manifestation of El Niño
