[A-AS12] Advancing Precipitation Science and Prediction: The WCRP Global Precipitation Experiment (GPEX)
Mon. May 25, 2026 5:15 PM - 7:00 PM
Poster Hall (Exhibition Hall 7&8, Makuhari Messe)
Accurate observation, modeling, and prediction of precipitation remain fundamental
challenges in Earth system science and are key to sustainable management of water
resources and disaster risk reduction. The World Climate Research Programme (WCRP)
launched the Global Precipitation Experiment (GPEX) as a Lighthouse Activity to advance
international collaboration in precipitation science. This session invites contributions
that address the four primary science questions of the GPEX Science Plan:
1. Uncertainty Reduction: Quantifying and reducing uncertainties in precipitation
estimates over land and ocean using advanced technologies and multi-source data
fusion.
2. Process Understanding: Advancing understanding of moist processes and their
interactions with atmospheric dynamics and other Earth system components.
3. Model Improvement: Reducing model errors and improving parameterizations
and physical-AI integration.
4. Applications and Capacity Development: Applying improved precipitation data and
forecasts to enhance regional resilience, early warning systems, and climate adaptation.
Research focusing on key precipitating systems - such as atmospheric rivers,
mesoscale convective systems, tropical cyclones, and monsoons - is especially
welcome. This session aims to bring together observationalists, modelers, and
application scientists to advance the understanding and predictability of
precipitation in support of the GPEX mission.
