潮水高度受月球和太陽引力影響。在農曆初一或十五，太陽、地球、月球成一直線，引力較大，稱為大潮（spring tide）。在上弦或下弦，月球、地球、太陽成一直角，引力較小，稱為小潮（neap tide）。 當月球在太陽和地球中間而且非常接近地球時，引力最大，此情況約 1.5 年出現一次。 除了引力外，風和氣壓均會影響潮水高度。前天晚上，天文大潮加上強烈東風把海水吹向岸邊，潮水高度上升至3米以上，西環、西貢、沙田等地出現水浸，或稱海水倒灌。昨晚轉吹北風，由於香港北面是陸地，風吹向離岸，因此潮水高度不及前晚高。 熱帶氣旋接近香港時，由於氣壓下降，海平面高度會上升。假如熱帶氣旋接近時適逢大潮及強風，可能造成沿岸地區水浸，稱為風暴潮（storm surge）。1937年香港經歷了一次嚴重的風暴潮，大埔潮水高度升至6米以上，沙田遭淹沒，造成嚴重傷亡。 過往香港很少在冬季出現海水倒灌，今次事件後，大家對潮水的認識可能多了一點點。<\/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-565","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\/565","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=565"}],"version-history":[{"count":2,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/565\/revisions"}],"predecessor-version":[{"id":769,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/565\/revisions\/769"}],"wp:attachment":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/media?parent=565"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/categories?post=565"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/tags?post=565"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
