CLIMATE & HIGH-IMPACT WEATHER (CHI) LABORATORY

Institute of Environmental Science & Meteorology

College of Science, University of the Philippines Diliman

RESEARCH THEMES

Climate Modeling and Analysis

The laboratory utilizes climate models to simulate future climate scenarios and assess the potential impacts of climate change and variabilities on regional and local scales. This analysis will provide valuable insights into long-term climate trends and help in developing mitigation and adaptation strategies.

Extreme Weather and Climate Events

The laboratory focuses on studying extreme weather phenomena such as tropical cyclones (TCs), heavy rainfall events, extreme heat and droughts; as well as sea level rise, flooding, storm surge, among others. The laboratory will investigate the underlying mechanisms, assess the frequency and intensity of these events, and develop early warning systems to mitigate their impacts. In particular:

Past (including event attribution) and future (projections) climate & impacts on TCs - frequency, intensity, rainfall, size, translation speed; & on other extreme events and natural climate variabilities
Use of the storyline approach (different scenarios based on plausible physical mechanisms)

Risk and Impact Assessment

By integrating climate and weather data with socioeconomic and environmental factors, the laboratory assesses the impacts of climate change, climate variabilities, and extreme weather events on various sectors. This analysis will aid policymakers, planners, and stakeholders in making informed decisions and formulating strategies for climate resilience.

Climate Services and Outreach

The laboratory collaborates with governmental and non-governmental organizations to provide climate services and information to different sectors. It will aim to enhance public awareness about climate change and variabilities, promote sustainable practices, and support policymakers in implementing effective climate-related policies and programs.
