Dr. Hassan Ahmadul, Technical Adviser of the Red Cross Red Crescent Climate Center in Bangladesh shared learnings on the triggers used for the 2020 Early Action Protocol (EAPs) activations for Cyclone Amphan and the Juen/July floods in Bangladesh. He compared the different Met Office Department models and their corresponding slight variations of the impact forecasts for how rural housing structures would be affected. Learnings for the cyclone trigger: 1.) Activation time for Cyclone Amphan was only 30 hours, we need more time to get ready. Hence the need to include a pre-activation trigger at -72 hours. 2.) Wind interpolation error from land fall to unions is +/30%. This is acceptable but may be improved by including recent observation data. 3.) The need to use multi-models – to not only depend on Bangladesh Meteorological Department (BMD). On Impact and Intervention, Dr Hassan noted that the records for ´Severely Damaged´ unions matched with the forecasted impact and the unions prioritized by the trigger model of the FbF project.
