熱帶氣旋襲港時，天氣報告常報道「颱風xx集結在北緯xx度、東經xx度」，有甚麼意思？ 緯度（latitude）及經度（longitude）是用來準確表達地球上位置的單位。把地球水平分為南北半球的線稱為赤道（equator）。從赤道分別向南及北畫出平行赤道的圓，稱為緯線（lines of latitude）。在赤道以北稱為北緯，以南稱為南緯。緯線的範圍由0-90度。 把地球垂直分為東西半球的線稱為本初子午線（prime meridian）。從本初子午線分別向東及西畫出平行子午線的圓，稱為經線（lines of longitude）。在子午線以東稱為東經，以西稱為西經。經線的範圍由0-180度。 地球並非球體，赤道半徑（6378.5公里）較兩極半極（6356.9公里）為大，準確計算地球上兩地的距離（弧線）將涉及複雜計算，因此我們假設地球為一球體，半徑6371.3公里。在這個假設下，每個緯度相距111.1公里（60海里） ，每個經度相距在赤道為111.1公里，在兩極則為0。 利用經緯度計算地球兩地距離及方位可用以下網址：http:\/\/williams.best.vwh.net\/gccalc.htm 當需要更高準確度（例如使用衛星定位系統時），我們把「度」再分為「分」及「秒」。一度有 60 分，一分有 60 秒，這與時間上的分和秒並不相同。當計算熱帶氣旋與香港的距離時，香港位置通常取為北緯 22 度 18 分（或 22.3 度），東經 114 度 10 分（或 114.17 度）。 了解上文後，你能找到以下廣告的錯誤嗎？<\/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-570","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\/570","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=570"}],"version-history":[{"count":1,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/570\/revisions"}],"predecessor-version":[{"id":749,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/570\/revisions\/749"}],"wp:attachment":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/media?parent=570"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/categories?post=570"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/tags?post=570"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
