There are insufficient observations to determine whether trends in such local phenomena exist, but recent studies suggest that conditions associated with such hazards have become more frequent across large parts of Europe in recent decades. These conclusions are in part based on work with Additive Regression Convective Hazard Models (AR-CHaMo) that have been developed using state-of-the-art reanalysis data and observations collected in the European Severe Weather Database (ESWD).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The CHECC project\nimproves AR-CHaMo by using newer reanalysis datasets with higher spatial and\ntemporal resolutions, such as ERA5, COSMO-REA6 and MERRA2. The added resolution\nis expected to better resolve the conditions that give rise to the convective\nstorms and hence to improved statistical models. More improvement is expected\nfrom additional observational data that is retrieved from media archives and thus\nenhances the severe weather database used for training the models. The robustness\nof the models will be investigated by applying them to different regions, e.g.\nEurope and a part of North America.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">CHECC uses\nthe models to investigate if significant trends in modelled hazard occurrence can\nbe detected both in the past and in future climate projections. Furthermore, CHECC\nstudies which part of these trends can be attributable to changes in\ntropospheric flow patterns, by assessing the impacts of any detected changes on\nthe underlying physical drivers of convective events. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Finally, CHECC will explore the use of convection-permitting reanalysis data, such as COSMO-REA2. This is of particular interest as climate projections are gradually becoming available at convection-permitting module resolutions. As part of this section of the study, predictor parameters will need to be modified owing to the higher spatial resolution which requires proxies that describe the convective storms themselves rather than their respective mesoscale environment. <\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"214\" height=\"132\" src=\"https:\/\/www.essl.org\/cms\/wp-content\/uploads\/image-7.png\" alt=\"\" class=\"wp-image-4661\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>ESSL is part of the ClimXtreme research network, funded by the German Ministry of Education and Research and carries out the project CHECC, part of ClimXtreme Module B.
