Lightening and Thunder
Lightening is a giant spark of electricity in the atmosphere between clouds, air or ground. When water vapor condenses into small ice crystals when it moves upwards in the cumulonimbus cloud. The ice crystals continues to grow till they gather enough mass to overcomes buoyance force this leads to a system where small ice crystals

Thunderstorms
Thunderstorm is a rain with thunder and lightening. They are of short duration occurring over a small area. Thunder storms occurs in an area where temperature is high and a strong convective updraft is possible. they are less frequent on water bodies due to low temperature. Thunderstorms occurs in a cloud called Cumulonimbus and can
Quasi Biennial Oscillation
The Quasi-Biennial Oscillation is a regular variation of the winds that blow high above the equator. Strong winds in the stratosphere travel in a belt around the planet, and every 14 months or so, these winds completely change direction. This means a full cycle takes roughly 28 months, making it the most regular slow variation

Madden Julian Oscillation
The Madden Julian Oscillation (MJO) is an equatorial travelling pattern of anomalous rainfall that is planetary in scale. The MJO can be defined as an eastward movement of clouds, rainfall, winds and pressure near the equator that typically recurs every 30 to 60 days. The MJO moves eastward at 5 meters per second across the

North Atlantic Oscillation (NAO)
The North Atlantic Oscillation (NAO) is one of the most prominent and recurrent patterns of atmospheric circulation variability. It dictates climate variability from the eastern seaboard of the United States to Siberia and from the Arctic to the subtropical Atlantic, especially during boreal winter, so variations in the NAO are important to society and for

El-Nino – Southern Oscillation
The name ‘ENSO’ is the close interaction between the atmosphere and ocean. It is an irregularly periodic variation in winds and sea-surface temperatures over the tropical eastern pacific ocean, affecting the climate of much of the tropics and subtropics. The warming phase of the sea temperature is known as El-Nino and the cooling phase is

Global Overturning Circulation (GOC)
Global overturning circulation is responsible for the transport of carbon and heat among the ocean basins and between the ocean and the atmosphere. The GOC can be conceptualized primarily into two connected overturning as follows – These two circulation cells are interconnected via upwelling in the southern ocean where deep water are mixed in the
