On the dynamics of extended breaks during 2017 monsoon

Southwest monsoon of 2017 was marked by two extended break spells during its second half. This study investigates the meteorological factors that contributed to the occurrence/sustenance of these breaks. It is found that the first break spell, that happened during 31 July-17 August 2017, was characterized by increased convection over northwest Pacific. On the other hand, the second spell during 01-11 September 2017 was associated with southward intrusion of midlatitude westerlies and increased convection over equatorial Indian Ocean.
