They bring hazardous weather events like blizzards, heavy snow, freezing rain, etc. They also supply fresh water through spring snow melt and maintain the soil and surface water balance in sub-humid and semi-arid regions. Any future changes in extratropical cyclone activity over Canada may have a significant impact on agriculture and the local economies of the various regions. Future changes in regional storm activity over Canada have not been studied in detail. Therefore, we examined potential changes in extratropical storm activity by the end of the century using data from six models from CMIP5 under historical and future (RCP 8.5) emission scenarios. A statistical analysis of selected storm activity indices, using a storm identification and tracking algorithm, revealed a decrease in the number of storms over the mid-latitude regions of Canada. However, intense storms with a longer duration are projected over all regions at the end of the century. A further investigation of the physical mechanisms revealed that a decrease in the meridional temperature gradient over the mid-latitude regions and shifting of the vertical wind shear are responsible for these expected changes in storm activity.","PeriodicalId":55434,"journal":{"name":"Atmosphere-Ocean","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135241891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Climatology of and Factors Contributing to Occurrences of Near-0°C Temperatures and Associated Precipitation At and Near Terrace, British Columbia, Canada","authors":"Émile Cardinal, Julie M. Thériault, Ronald E. Stewart, Hadleigh D. Thompson, Stephen J. Déry","doi":"10.1080/07055900.2023.2270560","DOIUrl":"https://doi.org/10.1080/07055900.2023.2270560","url":null,"abstract":"ABSTRACTOccurrences of near-0°C temperatures (–2°C ≤ T ≤ 2°C) are common in cold regions such as Canada, and these conditions can lead to freeze–thaw events and hazardous precipitation. Many locations in the Coast Mountains within the Canadian province of British Columbia (BC) are especially prone to near-0°C conditions. This study examines the factors that promote anomalously persistent near-0°C conditions, often with precipitation, in Terrace, a small industrial city within the Coast Mountains of northwestern BC. The climatology of near-0°C conditions and associated precipitation over the 1956–2020 period was developed using a combined network of weather stations and field data to study the atmospheric conditions and precipitation during periods of near-0°C conditions. Events with continuous near-0°C conditions generally had long durations, with a climatological mean of 11 h, which increases substantially if accompanied by precipitation (18 h), and even more if accompanied with freezing precipitation (38 h). The longest near-0°C event lasted 233 h and was associated with long-lasting snow and rain. By combining the field data information, large-scale weather conditions and long-term climatology, several factors that contribute to near-0°C conditions at Terrace were identified. These include the ocean’s proximity, the surrounding topography, persistent cloudiness, and diabatic processes associated with melting and freezing, although local factors linked with topographic features are also important. Collectively, this study has characterized and improved our understanding of Terrace's near-0°C conditions and its associated precipitation, and these insights can be used for improved forecasting of hazardous events in the area.Resume[Traduit par la rédaction] Les températures proches de 0°C (−2°C ≤ T ≤ 2°C) sont courantes dans les régions froides comme le Canada, et ces conditions peuvent entraîner des phénomènes de gel-dégel et des précipitations dangereuses. De nombreux endroits de la chaîne côtière de la province canadienne de la Colombie-Britannique sont particulièrement exposés à des conditions proches de 0°C. Cette étude se penche sur les facteurs qui favorisent des conditions anormalement persistantes proches de 0°C, souvent accompagnées de précipitations, à Terrace, une petite ville industrielle située dans la chaîne côtière du nord-ouest de la Colombie-Britannique. La climatologie des conditions proches de 0°C et des précipitations associées sur la période 1956–2020 a été élaborée au moyen d’un réseau combiné de stations météorologiques et de données de terrain afin d’étudier les conditions atmosphériques et les précipitations pendant les périodes de conditions proches de 0°C. Les événements avec des conditions continues proches de 0°C ont généralement une longue durée, avec une moyenne climatologique de 11 heures, qui augmente considérablement s’ils sont accompagnés de précipitations (18 heures), et encore plus s’ils sont accompagnés de pr","PeriodicalId":55434,"journal":{"name":"Atmosphere-Ocean","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135325933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
