Trade winds
Climatic factors influencing monsoon:
1Differential heating of continent and ocean → due to differential heat capacity of sun → Causes pressure differences between continent & ocean → low pressure on land/continent in summers and high pressure in oceans surrounding.
Atmospheric oceanic factors:
1Differential heating of continent and ocean
2[Illegible] disturbances → high pressure conditions sometimes delay the onset of southwestern monsoon.
3Jet streams → help in increasing intensity of monsoon (e.g., Tibetan jet stream, Tomasi jet stream).
4Localized rainfall events due to convection currents caused by heating and resultant loss pressure.
Oceanic factors:
1Ocean currents → Warm ocean currents like Somali current → increase intensity of monsoon.
2El-Nino → off Abnormal heating of eastern pacific ocean and replacing of cold peruvian current → cause of deficient rainfall in India.
3La-Nina → Abnormal cooling of eastern pacific ocean → cause most rainfall in India.
