释新闻｜本轮寒潮为何“极端性不强却需高度警惕”？

\u003cdiv class=\"rich_media_content\"\u003e\u003c!--NO_AD_ERROR_2--\u003e\u003cp\u003e1月17日至21日，寒潮将自西向东、自北向南影响我国大部地区，中东部地区将出现大范围雨雪冰冻天气。陕西、山西、河南、山东、湖北、湖南、安徽等地有暴雪。\u003c!--NO_AD_0--\u003e\u003c!--EOP_0--\u003e\u003c/p\u003e\u003c!--PARAGRAPH_0--\u003e\u003cp\u003e河南西部、湖北西部、湖南、贵州、重庆东部等地部分地区将出现冻雨。这次过程被认为是入冬以来中东部地区最强的雨雪冰冻天气过程。\u003c/p\u003e\u003cp\u003e1月16日，中央气象台首席预报员张涛在接受澎湃新闻（www.thepaper.cn）采访解读本轮寒潮天气时说，尽管此轮寒潮过程降水量不极端，但“冻雨的风险显著高于暴雪风险”，其致灾性不容小觑。\u003c!--NO_AD_1--\u003e\u003c!--EOP_1--\u003e\u003c/p\u003e\u003c!--PARAGRAPH_1--\u003e\u003cp\u003e“此次过程的‘强’主要体现在降水相态的复杂性上，特别是在秦岭淮河以南的南方地区。”张涛解释说，“1毫米的降雨是微不足道的，1毫米的降雪问题也不是很大，但是1毫米的冻雨影响会非常大。冻雨的致灾性与其量级并非线性关系，即使不大的冻雨量，也可能造成严重的交通中断、电力设施损坏等后果，这是此次寒潮需要特别警惕的原因。”\u003c!--NO_AD_2--\u003e\u003c!--EOP_2--\u003e\u003c/p\u003e\u003c!--PARAGRAPH_2--\u003e\u003cp\u003e他进一步解释说，对于南方地区而言，此次雨雪天气是随着冷空气而来的，冷空气来了以后相当于近地面已经形成低温层，这时无论是下雨、雨夹雪还是冻雨，最终都可能在地表形成冰冻。“因此，从这次寒潮过程特点来看，致灾性最强的，最需要我们警惕的恰恰就是在冰冻这一块儿。”\u003c!--NO_AD_3--\u003e\u003c!--EOP_3--\u003e\u003c/p\u003e\u003c!--PARAGRAPH_3--\u003e\u003cp\u003e此轮寒潮过程对于京津冀等北方地区而言，大风降温和雨雪影响并不极端，但对于可能出现冻雨和复杂降水相态转换的区域影响显著。\u003c/p\u003e\u003cp\u003e张涛再度提醒：“千万不要认为这一次寒潮过程致灾性不强，这是错误的认知。”他提醒公众，特别是南方地区居民，后期需高度关注冰冻等气象预警。\u003c!--NO_AD_4--\u003e\u003c!--EOP_4--\u003e\u003c/p\u003e\u003c!--PARAGRAPH_4--\u003e\u003cstyle\u003e.rich_media_content{--news-tabel-th-night-color: #444444;--news-font-day-color: #333;--news-font-night-color: #d9d9d9;--news-bottom-distance: 22px}.rich_media_content p:not([data-exeditor-arbitrary-box=image-box]){letter-spacing:.5px;line-height:30px;margin-bottom:var(--news-bottom-distance);word-wrap:break-word}.rich_media_content .qn-editor-copy p:not([data-exeditor-arbitrary-box=image-box]){letter-spacing:unset;line-height:unset;margin-bottom:unset;word-wrap:unset}.rich_media_content{color:var(--news-font-day-color);font-size:18px}@media(prefers-color-scheme:dark){body:not([data-weui-theme=light]):not([dark-mode-disable=true]) .rich_media_content p:not([data-exeditor-arbitrary-box=image-box]){letter-spacing:.5px;line-height:30px;margin-bottom:var(--news-bottom-distance);word-wrap:break-word}body:not([data-weui-theme=light]):not([dark-mode-disable=true]) .rich_media_content .qn-editor-copy p:not([data-exeditor-arbitrary-box=image-box]):not(.qn-editor-copy){letter-spacing:unset;line-height:unset;margin-bottom:unset;word-wrap:unset}body:not([data-weui-theme=light]):not([dark-mode-disable=true]) .rich_media_content{color:var(--news-font-night-color)}}.data_color_scheme_dark .rich_media_content p:not([data-exeditor-arbitrary-box=image-box]){letter-spacing:.5px;line-height:30px;margin-bottom:var(--news-bottom-distance);word-wrap:break-word}.data_color_scheme_dark .rich_media_content .qn-editor-copy p:not([data-exeditor-arbitrary-box=image-box]){letter-spacing:unset;line-height:unset;margin-bottom:unset;word-wrap:unset}.data_color_scheme_dark .rich_media_content{color:var(--news-font-night-color)}.data_color_scheme_dark .rich_media_content{font-size:18px}.rich_media_content p[data-exeditor-arbitrary-box=image-box]{margin-bottom:11px}.rich_media_content\u003ediv:not(.qnt-video),.rich_media_content\u003esection{margin-bottom:var(--news-bottom-distance)}.rich_media_content hr{margin-bottom:var(--news-bottom-distance)}.rich_media_content .link_list{margin:0;margin-top:20px;min-height:0!important}.rich_media_content blockquote{background:#f9f9f9;border-left:6px solid #ccc;margin:1.5em 10px;padding:.5em 10px}.rich_media_content blockquote p{margin-bottom:0!important}.data_color_scheme_dark .rich_media_content blockquote{background:#323232}@media(prefers-color-scheme:dark){body:not([data-weui-theme=light]):not([dark-mode-disable=true]) .rich_media_content blockquote{background:#323232}}.rich_media_content ol[data-ex-list]{--ol-start: 1;--ol-list-style-type: decimal;list-style-type:none;counter-reset:olCounter calc(var(--ol-start,1) - 1);position:relative}.rich_media_content ol[data-ex-list]\u003eli\u003e:first-child::before{content:counter(olCounter,var(--ol-list-style-type)) '.
