天氣寒冷加上大風時，人的感覺比較冷；同樣，天氣酷熱加上潮濕時，人的感覺比較熱。如何制定客觀的量度標準？ 我們對冷熱的感覺，受氣溫、風速、相對濕度及日照影響。我們體外有一層暖空氣保護，刮大風的時候，風把這層暖空氣吹走，身體便感覺寒冷。冬季美國及加拿大經常刮起大風，因此當局利用氣溫及風速制定「風寒指數」（Wind Chill），表示在特定的氣溫及風速下，人體感受的溫度。當風寒指數偏低時，市民應避免外出，以免皮膚被凍傷或出現體溫過低，造成危險。‭ ‬ 天文台的氣溫術語中，氣溫在8-12度稱為「寒冷」，7度或以下稱為「嚴寒」。當天文台預料市區氣溫跌至12度或以下時，便會考慮發出寒冷天氣警告，呼籲市民提高警惕，注意保暖及提防寒冷天氣影響健康。由於新界地區較為空曠，氣溫往往較市區為低，因此市民應留意身處地方的氣溫變化，不要過份依賴警告。 到了夏季，在濕度高的日子，由於皮膚上的水份較難蒸發，因此感覺較悶熱。假如氣溫不斷上升，戶外活動時又無法透過休息、喝水、穿著鬆身衣服、減少在陽光下曝曬等方法有效降溫，就有機會出現體溫過高、熱衰竭甚至中暑的現象。有見及此，美國國家氣象局根據氣溫及相對濕度制定「酷熱指數」（Heat Index）。當酷熱指數超過40度時，有機會出現熱衰竭；當指數超過55度時，隨時會出現中暑。 天文台的氣溫術語中，氣溫在28-32度稱為「炎熱」，33度或以上稱為「酷熱」。當天文台預料市區氣溫升至33度或以上時，便會考慮發出酷熱天氣警告。不過新界地區氣通常較熱，氣溫比市區更早達到酷熱水平，即使天文台未有發出警告，戶外活動時仍要採取預防措施。 除了風寒指數及酷熱指數外，其他常見的體感溫度指標還有「濕球黑球溫度」及「淨有效溫度」等，以至利用氣溫、相對濕度、日照及風速計算的「THSW 指數」。但由於計算比較複雜，始終未如風寒指數及酷熱指數般普及。<\/p>\n","protected":false},"author":2,"featured_media":3026,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"advanced_seo_description":"","jetpack_seo_html_title":"","jetpack_seo_noindex":false,"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":false,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"categories":[43],"tags":[],"class_list":["post-1540","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-43"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/i0.wp.com\/www.weather.org.hk\/news\/wp-content\/uploads\/2021\/01\/wccel.png?fit=450%2C221&ssl=1","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/1540","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/comments?post=1540"}],"version-history":[{"count":4,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/1540\/revisions"}],"predecessor-version":[{"id":3059,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/1540\/revisions\/3059"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/media\/3026"}],"wp:attachment":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/media?parent=1540"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/categories?post=1540"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/tags?post=1540"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
