天文台預測今晚天氣嚴寒，高地可能出現結冰現象。當氣溫接近冰點時，水的形態將出現變化，形成各種不同天氣現象。 天文台每天定時進行高空天氣觀測，並公佈香港上空氣溫垂直分佈。這條氣溫曲線將決定一切。 1. 雪（snow）：當高空氣溫低於0度時，雲內的水滴開始凝固成為冰晶，然後結合形成雪花。雪花下降的過程中，氣溫一直維持在0度以下才能到達地面。 圖：雪的氣溫垂直分佈（32F=0C, 25F=~-4C, 來源：美國國家海洋及大氣管理局） 2. 雨夾雪\/冰（sleet）：雪花在下降的過程中經過氣溫高於0度的空氣層，雪花融化為水滴。但其後氣溫再次低於0度，部分水滴重新凝固為雪花或小冰粒到達地面。 圖：雨夾雪／冰的氣溫垂直分佈（來源：美國國家海洋及大氣管理局） 3. 凍雨\/結冰（freezing rain\/ice）：跟雨夾雪\/冰相似，但雪花融化為水滴後未有足夠時間再次凝固，接觸地面或地面上較冷物件後才凝固為一層薄冰。凍雨\/結冰的危險性最大，道路結冰後變得濕滑，電線桿因電線結冰、負荷太重而倒塌，都是凍雨\/結冰的結果。 圖：凍雨的氣溫垂直分佈（來源：美國國家海洋及大氣管理局） 4. 雨（rain）：雪花在下降的過程中，低層氣溫高於0度，雪花全部融化為水滴。 有興趣的朋友，可以試玩這個降水模擬遊戲，自行製造不同的天氣現象。<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","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":[50],"tags":[],"class_list":["post-3829","post","type-post","status-publish","format-standard","hentry","category-50"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/3829","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=3829"}],"version-history":[{"count":7,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/3829\/revisions"}],"predecessor-version":[{"id":3921,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/3829\/revisions\/3921"}],"wp:attachment":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/media?parent=3829"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/categories?post=3829"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/tags?post=3829"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
