Coordination Mechanism (WCM) plays a key role in curating authoritative weather, water and climate information from the WMO Community to the United Nations and humanitarian agencies, thereby enhancing preparedness and early response efforts. Through the Early Warning for All Initiative (EW4All), WCM supports crisis-prone and conflict-affected regions with timely expert advice.For instance, during Tropical Cyclone MOCHA (May 2023), WCM curated critical information from various WMO Members and Centres, enabling a coordinated UN response (UNOCC, UNOCHA, UNHCR, IFRC) three days before the cyclone hit Bangladesh and Myanmar, protecting countless lives and livelihoods.By harnessing the collective expertise of the WMO Community, the WCM delivers timely, accurate and actionable insights, supporting effective anticipatory measures for the UN and humanitarian agencies.Weather4UNRelated podcasts Related video On 14 May 2023, Tropical Cyclone (TC) Mocha made landfall in Myanmar and impacted Bangladesh. During part of its track, the cyclone was one of the strongest ever recorded in the Bay of Bengal.

These advancements have led to more accurate predictions, benefiting operational meteorology, hydrology, oceanography, and climatology. However, there is a significant disparity in forecasting capabilities among WMO Members, with developed Members benefiting more from these advancements compared to developing and least developed countries due to limited resources.   WIPPS serves as a framework to address this gap for sharing operationally meteorological, hydrological, oceanographic, and climatological data. WIPPS allows Members to access and utilise the most advanced numerical models’ data and applications, leveraging scientific and technological advancements in Earth system modelling. WIPPS is facilitated by the WMO Information System (WIS), which supports international data exchange. By expanding the range of designated and participating centres, WIPPS enhances the global data-processing and forecasting system, enabling a broader range of applications to strengthen the world’s weather, climate, water and related environmental services.  WIPPS was previously known as the Global Data-processing and Forecasting System (GDPFS).</div> </div> <div class="mt-auto fill-white"> <div
