經過多天溫暖的天氣，冷鋒終於在內陸形成並向南移動，於今早橫過香港。冷鋒橫過香港時，香港天氣有甚麼變化？ 冷鋒（cold front）是冷暖氣團的交界，以下由 University of Illiois 提供的動畫可顯示冷鋒移動的過程： 由於暖空氣被抬升，因此冷鋒橫過時天氣會轉為多雲甚至有雨。 由於冷鋒的兩側是不同的氣團（air mass），因此冷鋒橫過時天氣變化相當明顯。風向會由東\/東南風轉為北\/西北風，氣溫及露點下降，氣壓上升。 冷鋒橫過香港時，香港西部地區（流浮山，屯門，赤臘角等）通常最先出現天氣變化。 在天氣圖上，氣溫\/露點\/風向出現明顯不連續的地方，就是冷鋒所在位置。   冷鋒約在北緯25度<\/p>\n","protected":false},"author":2,"featured_media":0,"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":[4],"tags":[],"class_list":["post-558","post","type-post","status-publish","format-standard","hentry","category-4"],"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\/558","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=558"}],"version-history":[{"count":1,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/558\/revisions"}],"predecessor-version":[{"id":760,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/558\/revisions\/760"}],"wp:attachment":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/media?parent=558"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/categories?post=558"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/tags?post=558"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
