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
