5influenced by global climate variation like El Niño and La Niña

reduced rainfall intensity in wet spell

6impact of tropical cyclone formation

Causative factors of Indian monsoon:

1apparent movement of sun and incidence of sunlight on earth leading to variation in ITCZ

[DIAGRAM DESCRIPTION: Shows sun position relative to earth during June and December, with ITCZ marked showing seasonal shift between June (when sun is overhead at Tropic of Cancer) and December (when sun is overhead at Tropic of Capricorn)]

2El Niño southern oscillation in pacific ocean impacting direction of trade wind causing El Niño and La Niña

3Indian ocean dipole i.e. variation in temperature in western and eastern Indian ocean

4formation of easterly waterhway from tibetian plateau

5Somalian jetstream intensifying monsoon wind

ITCZ

[DIAGRAM: Shows relationship between trade wind, equatorial current, monsoon wind, and S.E. trade wind currents]

Indian monsoon phenomena:

Indian monsoon is significant to 100 billion people in subcontinent and essential in growth and development of region
