報載昨天東涌懷疑出現海市蜃樓景象，甚麼是海市蜃樓？ 海市蜃樓（mirage）是由於空氣密度隨高度急劇變化，光線穿過時彎曲，造成景物上移或倒置的現象。海市蜃樓可分為上現蜃樓（superior mirage）及下現蜃樓（inferior mirage）兩種，見圖： （圖片取自慧師學科網） 空氣密度隨高度急劇變化的原因有兩個：第一是出現逆溫層，即高度上升時溫度不降反升，常見於香港冬季及春季；另一是強烈日照使地面溫度急劇上升，常見於沙漠地區。前者引致上現蜃樓，後者引致下現蜃樓。 雖然近年香港出現煙霞的日子上升，影響能見度；但在天朗氣清的日子，能見度可達50公里或以上，在赤臘角機場可以看到澳門大橋和燈塔。 延伸閱讀（英文）：http:\/\/www.islandnet.com\/~see\/weather\/elements\/mirage1.htm<\/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-582","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\/582","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=582"}],"version-history":[{"count":2,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/582\/revisions"}],"predecessor-version":[{"id":787,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/582\/revisions\/787"}],"wp:attachment":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/media?parent=582"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/categories?post=582"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/tags?post=582"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
