Introduction: Seafogisatypeoffogthatformsovercoastalregionswhenwarm,moistairpassesovercoolerwaters.Itposesasignificantchallengeforweatherforecastingmodelsduetoitscomplexityandsensitivitytovariousatmosphericconditions.TheWRFmodeliswidelyusedforsimulatingandpredictingvariousmeteorologicalphenomena,includingseafog.However,theimpactofverticalresolution,especiallyintheboundarylayer,onseafogsimulationhasnotbeenextensivelystudied. Methodology: ThestudyutilizestheWRFmodeltosimulateandpredictseafogunderdifferentverticalresolutions.Themodel'sinitialandboundaryconditionsareobtainedfromhigh-resolutionmeteorologicaldata,suchasseasurfacetemperatures,windfields,andatmosphericprofiles.Thesensitivityoftheverticalresolutionisexploredbyvaryingthenumberofverticallayerswithintheboundarylayer.Severalsimulationsareconductedwithdifferentverticalresolutionstoevaluatetheirimpactonseafogsimulation.
