So why the cancellations? Well, if a plane were to fly into that ash cloud it may lose power. An ash plume is made up ash, glass and tiny bits of rock. The glass is capable of hurting a plane's electronics and the rocks can damage its turbines. Those tiny bits of rock can heat up and stick to the engine's components resulting in a loss of power. Not to mention a lack of visibility for the pilot and harmful gases could be pumped into the cabin. As for how long this problem may persist...this could be a frequent issue. The Eyjafjallajokull Volcano has been very active as of late and shows no signs of calming down. Iceland sits right over a divergent plate boundary where two tectonic plates are in a constant state of seperation allowing magma and volcanic gas to reach the surface. Every now and then, as pressure from below builds, this volcano literally "burps" spewing ash high into the atmosphere. Let's hope for those stranded passengers that this ash clears in the next day or so but another plume may not be far behind.Thursday, April 15, 2010
Eyjafjallajokull...try saying that 3 times fast!

The Return of Winter?
I’ve had a few calls today from concerned viewers asking me what we can expect as that system pushes east. Luckily we dodge a bullet. Looking at the pic above you can see that that ridge of high pressure over Ontario that is blocking this storm’s track. As that western trough in the jet stream is trying to “dig” east it is being slowed by that “blocking high.” When a low is stalled we start to see an occlusion form as the cold air literally “catches up” to the warm air in advance of the low. That funny pink front you see is called an “occluded front” and it’s like a zipper being done up between the cold and warm front. Cold air starts to surround the low at the surface forcing the warm aloft and this weakens the storm. In short, this means that by the time this system crosses north of our region it will be a much weaker storm. For Peterborough we can expect showers (starting as early as tomorrow afternoon) with rain late Friday into Saturday. Communities to the north (Haliburton and Bancroft) may experience some thunderstorm activity…but no snow. So let’s be happy with the rainy forecast to round out the week. The rain is much needed and I’ll take showers over 20cm of wet snow any day.

Ola!
Here's another shot of the beach. Our CHEX TV group enjoyed a catered beach party with that amazing view and witnessed one of the most spectacular sunsets I have ever seen. Getting away from the beach was tough but I did manage to make a trip into a small Cuban village as well as a snorkeling trip on a huge catamaran. The sea life on that trip was unbelievable and as for the trip into town...let's just say the Cuban people are amazing. I think the biggest thing our group brought back to Canada was our impression of the people of this small Caribbean nation. Cuba is a poor country but the people are the among the happiest and the nicest I have ever met. This may have been my first trip to Cuba but it will not be my last and I have to send out a big thank you to Mary and the staff at Marlin Travel Peterborough for this amazing opportunity.
