I am so blessed to do what I do! Not only do I love the weather and everything about it, I get to correspond with people who are as passionate about it as I am. I am thrilled when their passion is enhanced by curiosity.
Earlier this week I received an email question from Ginny Stoddart from Aylesford, N.S. I was happy that she attached a beautiful photo!
Ginny wondered what type of cloud she saw and commented that it looked like a waterfall touching the Bay of Fundy.
The cloud is a fog roll. By definition, fog is a cloud whose base is touching the ground or, in this case, the water. Fog and clouds are formed by water vapour.
When a warm, moist air mass moves from the land over the cold water, the cold air just above the cold water will cool the air mass from below, bringing the temperature right down to the dew point allow for fog to form quite quickly. This type of fog is called advection fog.
At the time the photo was taken, the prevailing wind was moving drier air into the leading edge of the wall of fog, not allowing further formation, but holding it back and pushing it down, creating a waterfall effect.
I’ve witnessed it before, but never quite like this. Thanks to Ginny’s keen observation and curiosity, we all had a chance to see how incredibly beautiful nature can be!
This weekend in weather history
May is here and gardeners and golfers are itching to get out!
The first weekend of the month in the Maritimes is looking good, but that’s not always the case. Last year, it rained on both the first Saturday and Sunday in May. Nova Scotians got anywhere from 35 to 60 mm of rain across the province. On Prince Edward Island, 35 to 50 mm fell.
This weekend won’t be a warm one in Newfoundland and Labrador. In 1999, an early heat wave was building in during the first weekend of May: on the Saturday, it was 23 C in St. John’s and by Sunday the mercury soared to 26 in Corner Brook.
