Tropical Cyclone Herman Detected Again Over East Java, Says BRIN Researcher

TEMPO.CO, Jakarta - The tropical cyclone Herman that emerged two days ago entirely dissipated, however, the climate and atmosphere researcher from the National Research and Innovation Agency (BRIN) Erma Yulihastin warned that clouds from the storm are growing again over the southern part of East Java on Wednesday, April 5. 

“The direct effect of the strengthened cyclone Herman will be evident in heavy rainfall and strong winds hitting East Java,” said Erma. 

Based on the observation from the SADEWA or Satellite-based Disaster Early Warning System which BRIN developed, the remnants of cyclonic decay clouds have started to converge and grew into an expanding cloud cluster system, also known as a Mesoscale Convective System (MCS).

Erma argued that the convective cloud pattern that has continued to grow to the afternoon shows that the storm cloud cluster continued for more than four hours. At this stage, the expanding cloud cluster system can potentially turn into a tropical depression. 

“And then change a tropical storm that is commonly known as the tropical cyclone genesis or tropical cyclone seeds,” said the researcher. 

Reinforcement of cyclone Herman, which once reached level 5 strength and was classified as a super-cyclone, received full support from abundant moisture in eastern Indonesia due to the effect of the formation of two vortices in the Banda Sea. 

The two vortices or wind vortices in the Banda Sea said Erma, actually grew together with the vortices in the Indian Ocean which became the forerunners of tropical cyclone Herman.
