過去一個月，長江中下游受梅雨鋒（低壓槽）影響持續降雨，部分地區累積雨量已超過600毫米。 圖：過去一個月全國雨量分佈（來源：中央氣象台） 中央氣象台連續一個月發布暴雨預警，各地防洪形勢險峻。預料未來一星期雨勢將會持續，日本九州地區亦會受到影響。 圖：GFS預報未來7日累積雨量（來源：Tropical Tidbits） 另一方面，副熱帶高壓脊正覆蓋西太平洋及中國東南沿岸，下沉氣流令熱帶擾動無法發展，因此自上月中熱帶氣旋鸚鵡後，西太平洋一片平靜。要打破這個局面，就要等待副熱帶高壓脊北跳至較高緯度，將梅雨鋒推向北並讓出西太平洋的空間，等待南半球的東南信風跨越赤道後，受科氏力影響轉為西南風，提供熱帶擾動形成的條件。不過這可能是七月中以後的事了。 圖：GFS地面及500百帕天氣圖，副熱帶高壓脊（紅色部分）覆蓋西太平洋，有待北跳至較高緯度。（來源：Tropical Tidbits）<\/p>\n","protected":false},"author":2,"featured_media":2547,"comment_status":"closed","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":[40],"tags":[],"class_list":["post-2546","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-40"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/i0.wp.com\/www.weather.org.hk\/news\/wp-content\/uploads\/2020\/07\/SEVP_NMC_GISP_S99_EE30_ACHN_L88_PB_20200703000000000.jpg?fit=860%2C716&ssl=1","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/2546","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=2546"}],"version-history":[{"count":10,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/2546\/revisions"}],"predecessor-version":[{"id":2559,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/2546\/revisions\/2559"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/media\/2547"}],"wp:attachment":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/media?parent=2546"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/categories?post=2546"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/tags?post=2546"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
