亞洲週末天氣影響日食日狀況

現在距離 4 月 8 日星期一日全食還有不到 10 天。

With less than 10 days to go until the total solar eclipse on Monday, April 8, millions of people across Canada and the U.S. are planning to travel into the path of totality, which cuts across portions of Ontario, Quebec, and the Atlantic provinces.The big day is close enough that weather models are finally in range to start sorting out the general patterns expected to criss-cross North America that afternoon. And clouds are the all-important factor for viewing this cosmic splendour.It’s too soon for anyone to accurately or confidently issue a precise cloud forecast. But forecasters can see how conditions across North America that day are likely to hinge on the evolution of an active pattern halfway around the world in Asia.DON'T MISS: Everything you need to know for April's spectacular and rare solar eclipseUp until now, we’ve had to rely on historical data to suss out the probability of cloud cover during the eclipse. And early spring is a stormy time of year, with cloud-filled skies being more common than not across most of the Great Lakes and Eastern Canada on that important date.Asia’s weekend weather to influence Eclipse Day conditionsRight now, though, we can start to see the general position of ridges and troughs in the upper atmosphere. These features can tell us where unsettled weather is possible on the big day, the first clue about where clouds may obscure the total solar eclipse.The timeline starts this weekend as a trough filled with frigid air dips over Siberia. This feature high in the atmosphere over northern Russia will gradually migrate toward lower latitudes in the days ahead, eventually dipping over Alaska before swooping into British Columbia by the middle of the week.RELATED: How to safely watch the April 8 total solar eclipseThis would put the trough—and its associated cold air—around the western United States by next weekend. Cold air tends to amplify the jet stream, which can lead to more widespread unsettled weather near robust troughs and calmer conditions beneath sprawling ridges.A sharp trough over the western U.S. will likely force a ridge to build over eastern North America around the time of the eclipse. (The Weather Network)Lots of things can and likely will change over the next week, but this kind of setup is the first positive sign you’d want to see if you’re hoping for calmer conditions and a chance for clearer skies along the path of the total eclipse here in Canada.Potential storms are still a wildcardIt’s becoming increasingly unlikely that we’ll contend with any Alberta clippers or systems affecting the path of totality from the northwest. Forecasters will closely watch the development of Texas or Colorado lows next weekend, as these would be the likely drivers for make-or-break cloudiness during the eclipse.MUST SEE: Canada’s next solar eclipse could change the weatherBetween this potential pattern and historical cloud data, conditions for southern Ontario may be a coin toss. Different cloud layers and the depth of moisture in the atmosphere would play a role in conditions on April 8. Quebec and the Maritimes may get lucky with this setup, which may favour a lower risk for clouds.Forecasters will have a clearer picture of the upper-level pattern across Canada and the U.S. by Easter Monday, ultimately picking out the location of cloud-producing low-pressure systems across the continent.Stay with The Weather Network for all the latest news and information on the upcoming total solar eclipse, including updated forecasts and fascinating information about this once-in-a-lifetime experience.WATCH: How to capture the solar eclipse with your phone or DSLR cameraClick here to view the video

距離 4 月 8 日星期一日全食還有不到 10 天的時間，加拿大和美國數百萬人正計劃進入日全食路徑，該路徑橫跨安大略省、魁北克省和大西洋省份的部分地區。的日子已經很近了，天氣模型終於可以開始整理預計當天下午橫跨北美的一般模式。雲端是觀賞這宇宙壯麗景象的最重要因素。但預報員可以看到當天北美各地的情況可能取決於半個亞洲亞洲活躍模式的演變。確定日食期間雲層覆蓋的可能性。早春是一年中的暴風雨季節，在這個重要的日子裡，五大湖區和加拿大東部的大部分地區雲霧繚繞的天空更為常見。高層大氣中脊和槽的一般位置。這些特徵可以告訴我們在大日子裡哪裡可能出現不穩定的天氣，這是雲層可能遮蓋日全食的第一個線索。俄羅斯北部上空高層大氣層中的這項特徵將在未來幾天逐漸向低緯度地區遷移，最終在阿拉斯加上空下降，然後在本周中旬猛衝到不列顛哥倫比亞省。全食這將把到下週末，該低壓槽及其相關的冷空氣將在美國西部周圍形成。冷空氣往往會增強急流，這可能會導致強勁的低壓槽附近出現更廣泛的不穩定天氣，以及蔓延的山脊下的平靜條件。 （天氣網）下週，很多事情都可能發生變化，但如果你希望天氣更加平靜，並且有機會看到沿途天空更加晴朗，那麼這種設置是你想要看到的第一個積極信號。這裡的日全食路徑。預報員將密切關注下週末德克薩斯州或科羅拉多州低壓的發展，因為這些可能是日食期間雲量成敗的驅動因素。模式和歷史雲資料之間，安大略省南部的情況可能就像拋硬幣一樣。不同的雲層和大氣中的水分深度將在4 月8 日的天氣情況中發揮作用。有更清晰的了解。包括更新的資訊關於這一一生一次的體驗的預測和有趣的資訊。
