Option 1: A violent rotating column of air extending from a thunderstorm to the ground. This description refers to a tornado, a weather phenomenon that occurs during severe thunderstorms. It is not related to E1 Nino.

Option 2: The deflection of the ocean currents in the northern and southern hemispheres due to the rotation of Earth. This description refers to the Coriolis effect, which causes ocean currents to curve as a result of the Earth`s rotation. Although this is a natural phenomenon, it does not specifically denote E1 Nino.

Option 3: The anomalous widespread warming of the sea surface of the tropical east and central Pacific Ocean. This is the correct description of E1 Nino. E1 Nino is a climate pattern characterized by abnormally warm ocean temperatures in the eastern and central Pacific. It is associated with disruptions in weather patterns around the world.

Option 4: The revolving tropical storms of the Caribbean and Gulf of Mexico. This description refers to hurricanes, which are rotating tropical storms. While E1 Nino can influence the frequency and intensity of hurricanes, it does not specifically refer to them.

Therefore, the correct answer is option 3, as it accurately describes the phenomenon of E1 Nino.
