Cyclones's effect on monsoon onset
Global warming impacts the monsoons in its onset, withdrawal, seasonal total rainfall and extremes. It also affects the cyclones over the Indian Ocean and typhoons over the northwestern Pacific Ocean.
Cyclones's effect on monsoon onset
Global warming impacts the monsoons in its onset, withdrawal, seasonal total rainfall and extremes. It also affects the cyclones over the Indian Ocean and typhoons over the northwestern Pacific Ocean.
Currently, cyclone formations are being seen in the pre-monsoon season due to the influence of a warmer Artic Ocean on the winds over the Arabian Sea.
The monsoon is also affected by the three tropical oceans"— Indian, Atlantic and Pacific; the 'atmospheric bridge' from the Arctic; the oceanic tunnel as well as the atmospheric bridge from the Southern Ocean.
Since the circulation of winds around the cyclones is in the anticlockwise direction in the northern hemisphere, the location of the cyclone is critical as far as the cyclone's impact on the monsoon is concerned.
Fortunately, a late monsoon onset does not necessarily indicate a monsoon deficit. But, this year is unique with an impending El Niño. The impact of the phenomenon is being prepared for by the globe and especially Indian, with necessary preparations on the economic as well as the agricultural front.
• a 'bridge' refers to two faraway regions interacting in the atmosphere
• a 'tunnel' refers to two remote oceanic regions connecting withing the ocean.
