World Meteorological Organization

Further to the previous announcement here, WMO is pleased to announce that the Compendium of Findings on the Effects of Climate Change on Weather Hazards and Analysis of the Impacts of Climate Change on Aviation Operations, is now available under the WMO e-Library, here.

Climate change, often manifesting through more frequent, more intense weather events, sometimes in locations that are different to the ‘norm’, has a profound impact on the aviation industry. Increasingly frequent extreme weather events and more intense hazardous conditions such as tropical cyclones and clear-air turbulence can disrupt the operations of airports and air spaces locally but with wider knock-on ‘network effects’ regionally and sometimes globally.

With WMO’s support, the aeronautical meteorology community is working towards strengthening its support to the International Civil Aviation Organization (ICAO) and other industry partners to help their efforts to adapt, mitigate, and build resilience, as a response to a changing climate.

As a follow-up to the 2020 survey conducted by the Standing Committee on Services for Aviation (SC-AVI) on the impacts of climate change and variability on aviation and on the basis of its main results (available here), the SC-AVI Expert Team on Weather and Climate Science for Aviation Applications (ET-WCS) has consolidated into a Compendium the findings of the latest assessments of effects of climate change and variability on weather hazards and extreme events, and consequential impacts on aviation.

The 2024 edition of the Compendium has been published by WMO as AeM-SERIES No. 9 and is available here.
