I'm sorry I haven't been blogging for a while-internet connection down, and blogger is under maintenance.
A lot of you have sent me emails asking questions and I generally answer them back via email, however I have taken a few questions so here they are...your Q's A's.
Why is Toronto often warmer than its surroundings?
This is known as the heat island affect. Due to the heat given off by buildings vehicles and people in a large city like Toronto and the heating by the sun of a city's dark surfaces like pavement the temperature can be 1C to 2C warmer in the day than if the city wasn't there. At night it's even more dramatic. On a calm, clear night temperatures can be as much as 12C warmer.
What's the difference between a meteorologist and a weather specialist?
A meteorologist is someone with a four year degree in meteorology or atmospheric science. A weather specialist is someone with weather knowledge but hasn't studied or completed specific course work in the discipline.
What is dewpoint?
Dewpoint (Td) is the point at which the air must be cooled to to become totally saturated. If the temperature is below freezing it is sometimes called the frost point. As the air temperature gets closer to the dewpoint temperature the humidity increases. Once the temperature dips to meet the dewpoint temperature and the air becomes totally saturated the water vapour starts to condense into water droplets. When this happens at the surface we get fog.
When will temperatures get back to normal?
It looks like we'll see more fall-like weather next week. Temperatures will heat up again from now until the weekend but start to become unsettled and more seasonal by the middle of next week. A low pressure system looks like it's finally going to pull a little of the cold air into Ontario from the western provinces.
Will we have a snowy winter?
Expect more snow than last year. A La Nina winter is shaping up. That normally results in near seasonal temperatures and above normal precipitation.
There you have it. Enjoy the climate change .
