Mountain snowpacks act as a natural reservoir for storing winter precipitation until summer months when downstream water demand is greatest. In the past, snowmelt usually began in late May or early June, thereby helping to sustain water requirements for downstream needs.<\/p>\n<p>However, climate change has been thawing the snowpack much earlier, sometimes as early as March in some regions, and replacing snow with rainfall, according to CTV News Canada. This early thawing and increased precipitation is making an already arid region increasingly at risk of summer water scarcity, a new study from the University of Colorado Boulder has found. From 1950 to 2013, the amount of water stored in snowpack plunged in more than 25 percent of the mountainous areas of Western North America, according to the study, published in the journal Nature Communications Earth &amp; Environment.<\/p>\n<p>This is happening \u2013 in part \u2013 because more snow is melting during winter and spring, blurring the boundaries between seasons, per the study. This means there will be less water available for later in the year when it is needed. \u201cOn average and in every mountainous region that we looked at, snow melt is occurring closer in time to when it fell,\u201d lead author Kate Hale, who conducted the research as a University of Colorado Boulder graduate student, said in a statement, reports The Hill. \u201cThe timing of water availability is shifting toward earlier in the springtime, with less snow melt and water availability later in the summertime,\u201d added Hale, who is now a postdoctoral associate at the University of Vermont.<\/p>\n<p>States and regional water managers use the \u201csnow water equivalent\u201d on April 1 every year to determine the amount of water contained in snow, enabling them to forecast water availability for the coming year. But Hale and her colleagues felt that having just the April 1 snapshot was insufficient, as it doesn\u2019t demonstrate whether snow slowly accumulated over the previous six months or if it fell in one lump sum just days prior to the measurement. So, using two publicly available data sources, they set about creating a Snow Storage Index (SSI), that incorporates both the timing and the amount of snowfall, as well as snowmelt, before and after April 1, according to the study.\u2018<\/p>\n<p>High scores on the snow storage index \u2014 a number as close to 1.0 as possible \u2014 occurred in places where snowfall is very seasonal, such as in the Cascades. But in Colorado\u2019s Rocky Mountains, the scores were lower \u2014 between 0 and 0.5 \u2014 indicating that snow both accumulates and melts throughout the colder half of the year. The study also found that the mountain ranges along North America\u2019s western coast, which are highly dependent on snowpack meltwater in spring and summer, could endure \u201ca painful adjustment.\u201d<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.digitaljournal.com\/tech-science\/early-snowmelt-in-western-mountains-means-drier-summers-more-wildfire-risk-study\/article\">Digital Journal<\/a><br \/>\n[\/newsletter_lock]<\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/vaufien\/early-snowmelt-in-western-mountains-means-drier-summers-more-wildfire-risk-study\/\">Early snowmelt in Western mountains means drier summers, more wildfire risk: study<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[22],"tags":[8479,10135,606,607,608,10136],"class_list":["post-114499","post","type-post","status-publish","format-standard","hentry","category-news","tag-early","tag-snowmelt","tag-vau_viikkokatsaus","tag-vauen","tag-vaufien","tag-western-mountains"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/114499","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/comments?post=114499"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/114499\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/media?parent=114499"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/categories?post=114499"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/tags?post=114499"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
