今天密雲有雨，風也頗大，是典型的東風潮天氣。  影響香港的寒潮可根據風向分為兩類，第一類是北風潮（northerly surge），風向轉為北風並帶來明顯降溫。第二類是東風潮（easterly surge），風向轉為東風並帶來密雲有雨的天氣。 東風潮發生時，天氣圖上的等壓線會出現「V」形，並沿著中國東南沿岸伸展。 此時香港會吹起東風，離岸及高地可能吹強風。如果高空吹東南\/南風的話，較暖的東南\/南風遇上較涼的東風便會被抬升，形成雲和雨。不過有些東風潮較為乾燥（例如初秋時），除了東風增強外，香港天氣不受影響。 東風潮是中國內陸的高壓區移至上海附近的結果。當高壓區繼續東移，地面的風向轉為東南，風勢便逐漸緩和，天色漸轉明朗。<\/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-560","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\/560","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=560"}],"version-history":[{"count":1,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/560\/revisions"}],"predecessor-version":[{"id":758,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/560\/revisions\/758"}],"wp:attachment":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/media?parent=560"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/categories?post=560"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/tags?post=560"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
