Introduction
- SST > 26℃- Ocean
- 5° and 30° latitude
Why me interested with this study?
- TC is a beautiful phenomenon
- Many small Island
- Banda Sea is Very large and deep
- Global impact factor

TC LILI 2019
In Maluku Barat Daya Island
SST Anomaly 155 157
Conclusion
1/ Banda Sea has a big supply for the formation of tropicalcyclones.
2/ Although the anomaly SST totally different between twotropical cyclones but warm of the ocean gave us a prove thatSST becomes the main factor.
3/ After SST was constantly warm, that can make thedynamical atmospheric above the Banda Sea give a response(sea-air interaction).
Many thanks to:
- Mr. Bodo ZESCHKE (Center Vlabs, Melbourne) give us more experience & New knowledge of Meteorological Satellite with more study case and discussion.
- Mr. Aki SHIMITZU (JMA) develops SATAID software for us especially (Indonesia) in the tropical regions.
- Mr. Jeff Wilson & Mrs. Agnes Lane
Terima KasihThank you. Question?
