瑪姬與貓咪家庭@英國

  
記得上星期日早上才下大雪(點我可見照片)
下午老公來接我下班還比平常早到
怕早上忘記穿外套出門的我若又吹風會感冒
巧的是一起進家門的我們過沒多久
就聽到外頭超響的一陣淅瀝嘩啦
心裡正奇怪今天下的雨怎麼如此大聲
走到後園玻璃門前才發現下起了HailStones冰雹


好加在老公今天迅速地提早來接我回家
避免了這場還算蠻大的HailStones冰雹
不敢想像在路上遇到這樣天氣開車真是危險說








才不到五分鐘後園已經下不少HailStones冰雹


連樓上屋頂也積了不少冰雹細碎
今年四月份的天氣真是每天都讓人意外
跟爸媽講Skype還聽他們抱怨天氣熱得受不了
看看英國這裡的氣溫出門仍然是好冷
出門時大外套圍巾手套可都是一樣少不了要穿著
每當有出現的短暫陽光反而覺得特別珍惜

 

※HailStones冰雹形成的原因-from BBC - Weather Centre



 

Hail is produced inside storm clouds and is made of solid ice. Hailstones can grow to dangerous sizes before they fall and have to be at least 5 mm (0.2 in) across to be considered as hail. If the particles of opaque ice are smaller than this they are known as 'soft hail' (graupel or snow pellets).

The hazards of hail?

Hail occurs when ice pellets falling from the top of the cloud collect a film of moisture as they descend. The moisture freezes when the pellets are carried back to the top by upcurrents. As this process is repeated the hailstones grow in size and each trip through the cloud adds a new layer of ice. Once hailstones become heavy enough they will fall to the ground and can be a really dangerous weather hazard. Most are smaller than 2.5 cm (1 in) in diameter, but some can be as big as tennis balls or even grapefruit size. The largest can weigh a little under 1 kilo and fall at more than 50 metres per second. Hail storms can devastate entire fields of crops in a few minutes, flattening and bruising the growing plants. The biggest hailstones in the world tend to fall in north-east India. In Britain there were last hailstorms with tennis ball-size hail stones in Horsham in 1958 (5 September) and Wokingham in 1959.
