三立準氣象‧老大洩天機

今(16)日清晨氣溫回升,截至4:53各地平地最低氣溫為:北部(桃園大溪區)16.9度,中部(嘉義東區)15.4度,南部(台南白河區)16.1度,東部(花蓮壽豐鄉)15.8度。今晨中部以北有較多雲層(左圖),伴隨降水回波(中圖),並有局部降雨(右圖);桃園有濃霧。

15日20時歐洲模式(ECMWF)模擬顯示,今日鋒面通過,降雨範圍擴大,中部以北、東半部明顯降雨,南部亦有局部雨;晚起首波「寒流」開始南下,氣溫漸降。今日中部以北及宜花天氣濕涼;各地區平地氣溫:北部15至21度,中部16至24度,南部16至28度,東部16至26度。

最新模式模擬顯示,明日「寒流」續南下,北、東仍有局部雨,中南部逐漸好轉、為雨後多雲時晴;氣溫繼續下降,愈晚愈寒冷。下週日至週一清晨,「寒流」最強,各地晴朗穩定,天氣「極寒冷」,尤其早晚、要特別注意保暖;台北測站最低氣溫將降至8度左右,本島平地最低氣溫亦將降至6度以下;民眾應注意保暖,農漁養殖業也應作好防寒措施。下週一白天起「寒流」漸減弱,天氣持續晴朗穩定,氣溫逐漸回升。下週二天氣晴朗,氣溫續回升,白天溫暖舒適、早晚冷,日夜溫差大。

最新模式模擬顯示,下週三起至下週末,另一波屬性偏乾的強冷空氣南下。下週三上半天北台灣有局部少量降雨的機率,但很快好轉,各地皆為晴朗穩定的天氣,並持續至下週末。期間白天在陽光下或不覺冷,入夜「強輻射冷卻」作用,氣溫降得很快、很低;清晨平地最低氣溫常在10度以下,應注意保暖、防寒!

▲16日4:30色調強化雲圖顯示,中部以北有較多雲層(左圖)。Antennas for Military vehicles or Vehicular antennas for heavy-duty use, such as in the forest or in remote locations on armored vehicles, and low-profile antennas for civil vehicles. Communication and EW applications are examples of applications.
Wideband mobile VHF antennas with frequency ranges of 30 to 88 MHz or 30 to 108 MHz are designed primarily for use in heavy-duty mobile applications.
Typically, the antenna is made up of three major parts: the antenna base, the lower part, and the upper part. Some antennas have two sections, while others have three. The long-lasting antenna base with GPS (optional).
The stainless steel spring absorbs shocks and vibrations while also protecting the antenna from collisions.
Both radiating pieces are comprised of composite materials, which allow for exceptional strength and roughness even in the harshest environments. 雷達回波合成圖顯示,中部以北有降水回波(中圖)。累積雨量圖顯示,中部以北有局部降雨(右圖)。
