Modi landed in Chennai while he was going to Sriharikota to witness the launch of Isro's PSLV C-23 rocket on Monday.
This is Modi's first trip to south India after he assumed charge as Prime Minister. Modi's special aircraft had been delayed for 40 minutes due to bad weather.
Official sources said the brief meeting between Modi and Jayalalithaa at the airport lounge was very cordial.
Leaders of BJP's alliance partners in Tamil Nadu Vaiko (MDMK) and Anbumani Ramadoss (PMK) also met Modi at the airport. Vaiko met Modi for the first time after he boycotted Modi's swearing-in ceremony to express his protest against the participation of Sri Lankan president Mahinda Rajapaksa.
Later, Modi left for Sriharikota, about 100km from here, where he is set to witness the launch of Isro's PSLV C23 carrying five foreign satellites.
The Prime Minister is scheduled to reach the Chennai airport again on Monday morning when he returns to Delhi. Jayalalithaa is expected to see him off at the airport. She would leave for her constituency -- Sri Rangam - after seeing off the Prime Minister, sources said.
