write two differences between the monsoon and retreating monsoon season in India

Dear student,

​​​​​Your question seems to be a bit ambiguous because the monsoon is the overall phenomena and retreating monsoon is just a part of it. However, if you wanted the differences between north-east monsoon and retreating monsoon here is the answer.
 

North East Monsoon	Retreating Monsoon
North-East Monsoon winds blow during the winter season.	Retreating monsoon occurs during October and November
Northeast Monsoon winds bring rainfall over the coastal region of Tamil Nadu	The retreating Monsoon is marked by clear skies and rise in temperature

Regards,
