ABOUT THE PLATFORM
Independent insight. Scientific responsibility.
Tropical Weather Intelligence is being developed as an independent scientific communication and consultancy platform focused on the tropical atmosphere, extreme weather, and climate-related hazards. It aims to make complex analysis accessible without compromising scientific context.
TWI is independent and is not presented as an official agency forecasting or warning channel.
SELECTED TECHNICAL PORTFOLIO
Applied meteorology. Real-world decisions.
Selected professional projects and scientific work undertaken by TWI’s founder before the creation of the independent platform.

FOUNDER & SCIENTIFIC DIRECTOR
From atmospheric science to real-world impact.
Bridging atmospheric research, operational meteorology, and science-based risk assessment to support informed decisions.
Dr. Deni Septiadi
Founder & Scientific Director · Associate Professor of Meteorology
An Indonesian meteorologist and academic with over two decades of experience in operational weather forecasting, atmospheric dynamics, extreme weather, meteorological risk assessment, and applied scientific projects. He served as Director of the Indonesian State College of Meteorology, Climatology and Geophysics (STMKG) from 2024 to 2026, following earlier responsibilities in academic leadership, student affairs, and institutional cooperation.
His expertise spans tropical atmospheric dynamics, lightning physics and thunderstorm electrification, aviation meteorology, satellite and radar observations, numerical weather prediction, and hydrometeorological hazards.
As a Principal Investigator and Meteorological Aspect Leader, he has contributed to nuclear power plant site evaluation, meteorological safety studies, upper-air atmospheric monitoring, and environmental risk assessments through assignments involving Surveyor Indonesia, Renuko, BATAN, and BRIN-supported research.
His work also includes interdisciplinary flood-risk research in the Ciliwung basin and atmospheric monitoring using radiosonde and GNSS observations.
Through Tropical Weather Intelligence (TWI), he aims to advance independent scientific analysis, strengthen research collaboration, and communicate atmospheric evidence to support science, media, and society.

PLANNEDMembership will be published only after invitations are accepted and roles are agreed. No external appointments are claimed at this stage.
EDITORIAL & SCIENTIFIC STANDARDS
Evidence first. Context always.
Attribution & reproducibility
Published analyses should identify authors, publication dates, data sources, methods, limitations, and corrections when applicable.
Clear publication labels
Research previews and expert commentary are distinct from peer-reviewed journal articles and operational weather warnings.
Editorial independence
Sponsored or commissioned work, where applicable, should be transparently disclosed and separated from independent editorial analysis.
