World Weather Lake Effect Snow
Lake effect snow can cause large local variations in snow depth with 50 cm of snow accumulate over the course of a few days near the shore and a few miles inland from the lake shore there may be no snowfall at all. Lake effect snow does occur in regions away from the great lakes (for example along Lake Baikal in Russia) but it is far more pronounced and and destructive to ground and air transportation around the great lakes.
Lake effect snow occurs when a mass of freezing air moves down from the Arctic over a body of warmer water, creating instability in the atmosphere above the lakes. As a consequence, clouds build and develop over the lakes and, as they move downwind, develop into snow showers and squalls.
The water temperature of the Great Lakes lags behind the atmosphere in cooling through early winter, as water holds its heat far more readily than land. The heating from below results in instability in the air during cold outbreaks. This instability mixes warm, moist air near the surface of the lakes into the lowest 1 to 1.5 km of atmosphere. Rising air rapidly reaches saturation, and the result is shallow cumuliform clouds, frequently aligned in bands parallel to the low-level wind. By January, ice covers most of the lakes\’ surface area, cutting off or reducing the heat supply.
The distribution of lake effect snowfall in the Great Lakes area depends upon several factors: the position and direction of weather systems, the lake water temperatures and its variations, and the strength and direction of the winds. Topographic differences on the lee of the Great Lakes also affect the intensity and distribution of snowfall. On the eastern and southern shores of the Great Lakes, lake effect snowfall contributes between 30% and 50% of the total winter snowfall.
Winds from the Arctic generally blow from the west or northwest, causing lake effect snow to fall on the east or southeast sides of the Great Lakes. Whether or not an area gets a large fall of snow from lake effect snow is dependent on the direction of the winds, the duration they blow from a particular direction, and the size of the temperature differential between the lakes and the air above. Cold air holds very little moisture and the low level of the atmosphere is quite unstable. Therefore clouds can form very quickly, condensation occurs and snow falls.
In late 1977 a storm hit the southeast of Lake Huron around London, Ontario. In just three days from December 7th to 9th 100cm (39 inches) of lake effect snow fell on the region. This snowfall was made worse by the 60mph winds causing huge drifts.
However the largest snowfall recorded that was attributed to lake effect occurred in January 1966. In a five day period from 27th to 31st, 259cm (102 inches) of snow fell in Oswego, New York. Half of that total fell on the 31st.

Enjoy a Desert Safari in Dubai at a Bedouin Camp
The Bedouins we see today are loosely referred to the indigenous tribes traversing the desert dunes in the Middle East. Their legacy and heritage however, go much deeper as they are one of the oldest tribes to occupy the sand dunes.
Initially wandering nomads, the Bedouin that desert tours in Dubai now take tourists to interact with are more sedentary then their ancestors.
A very popular attraction and experience for tourists coming on sightseeing tours in Dubai, Bedouin camps are located deeper into the desert. Common locations to sight one? The wadis and the hilly desert regions.
There are very few camps accessible to the public however and even fewer are open for Dubai sightseeing tours. The Bedouin camps are open for touring are a splendid way to get to know the original Arab way of life.
Tourists on desert safari excursions in Dubai can get to sample food cooked the traditional Bedouin way and have a look at the goods and produce they create for a living. These are a friendly people and tourists will enjoy a round of their camping settlement.
Some desert tours in Dubai also provide opportunities for overnight camping in the desert, where after a night of entertainment and dining the Arab way, there are accommodations made to sleep in the camp. For tourists who prefer settings that are more luxurious, the Hatta Fort Hotel with their air-conditioned tents deserve a mention.
You can fix up your Bedouin desert camping in Dubai with a tour company like One World. They currently have the best deals.

Why Does the Lake Erie Dead Zone Exist?
In the summer, the water in the Great Lakes separates into two layers. The top layer is warmer than the bottom one, it receives the sunlight, and it mixes with oxygen from the air. The bottom layer is cooler than the top layer, it is usually dark, and it is cut off from the air so it cannot re-supply its oxygen.
The Western Basin of Lake Erie is shallower than the typical thickness of the upper layer of water. Winds are able to keep the whole water column stirring, so there is plenty of opportunity for oxygen to dissolve into the water from the air. The bottom of the Central Basin is a broad, shallow plain that is slightly deeper than the typical thickness of the upper layer. Therefore, the bottom layer is relatively thin and contains a relatively small volume of water. In the deeper Eastern Basin , the bottom layer is much thicker and contains more water.
If there is much phosphorus in the water, it acts like fertilizer, and more algae will grow in the warm, sunlit top layer. Eventually these algae will sink into the dark bottom layer, where they stop growing and begin dying. Bacteria and fungi then decompose the plant organic matter. Bacteria and fungi also need oxygen to live, and they use what is available in the water. Because the bottom layer is cut off from the air, over the summer, less and less oxygen remains in the water. If there is a small volume of water and a lot of decomposition going on, as exists in the Central Basin , the oxygen will be used up faster than if there is much water and/or little decomposition. This is not a problem in the Eastern Basin largely because of the much greater volume of water in the bottom layer.
Each autumn, the top layer cools, and the wind mixes it deeper and deeper into the bottom layer. Eventually the whole water column is the same temperature, and the wind can again mix it from top to bottom and the oxygen can be restored from the air. In the Central Basin , this phenomenon typically occurs in early to mid-September, when oxygen is restored from top to bottom.

A Marvelous Getaway To Malta Or Marrakech
In the mood to really get away but don’t want to spend all day in an airplane? Why not head to Malta or Marrakech – each under 4 hours from London by plane and each with a unique delicious foreign flavour.
If you’re a beach person, definitely go to Malta. Situated off the coast of Sicily, the officially-named ‘Republic of Malta’ is a small island, so it has tons and tons of beautiful beaches to choose from! In fact, Malta’s beaches are one of the reasons this destination is so popular among tourists.
There is no shortage of aquatic activities to choose from in Malta. You can go paragliding, windsurfing, wakeboarding, water skiing, snorkeling, or take a Malta Diving tour and explore Malta’s diverse underwater world of reefs, caves, and wrecks.
Malta is not all just fun and sun, though. Malta tours will open your eyes to all there is to see and do on this memorable island – Malta possesses a rich cultural history that has rendered it a virtual open air museum.
Malta Sightseeing Tours will reveal some of the oldest known structures to mankind. As a Malta tourist, be sure to check out Hypogeum, a UNESCO world heritage site. This temple was discovered in 1902 when a stonemason uncovered the remains of over 7,000 people, dating back to 3600 BC, while he was laying the foundations for a house.
If you’re more of a city person (the idea of sitting on a beach all day bores you) then head to Marrakech. With so many things to do in Marrakech, boredom will certainly not be one of the sentiments you experience during this trip!
From the beautifully-decorated riads hidden behind inconspicuous doors in dusty alleys, to the wonderfully chaotic and colourful souks, Marrakech is just so wonderfully different. This city simply exudes an exotic feel.
If you’re looking for what to do in Marrakech, you won’t have to look for long. Chances are you’ll end up at the Djemma el Fna square, located in the Medina (or old quarter of Marrakech), without even trying. Here, snake charmers and performers will enchant you while henna artists and vendors try to befriend you.
Sightseeing in Marrakech will undoubtedly be a jam-packed activity. The Koutoubia Mosque, Yves Saint Laurent’s Jardin Majorelle, the Marrakech Museum, and the Palais de la Bahia are only a few of things you must see in Marrakech. And if you have any energy left, the nightlife in Marrakech can be quite lively, if you’re willing to look for it.
So, go to Malta and lounge about on the beach in between visits to some amazing historical sights or go to Marrakech and wonder at the beauty of its culture. Either way, a marvelously exotic vacation is only a few hours away.
Lake Ontario Walleye Fishing – Where to Fish, and How to Fish & Tips
The walleye are probably best known for their large eyes that allow them to see very well even when it’s dark and the sharp teeth located in their jaws and the roof of their mouth. They are a nocturnal species of fish so the best results usually come with night fishing but this doesn’t mean this is the only time you can catch walleye. You can get some really good results on overcast days as well. The walleye are normally a dark yellow to green color with a white underside. They are equipped with two sets of dorsal fins, one of which has spines and the other has approximately twenty soft rays. They can also grow to some fairly decent sizes.
The walleye is a native fish to Lake Ontario in New York and it is one of the most sought after species in this area. In fact, Lake Ontario is considered one of the hot spots found in New York for walleyes. Lake Ontario is actually the smallest out of all the Great Lakes but many people still compare it to Lake Erie because they are close to being the same size when it comes to length and width. However, the main difference is that Lake Ontario is much deeper, which means that when it comes to volume it holds four times as much water, making it the prefect home for the walleye.
The walleye are not very cautious eaters meaning they will strike at your bait regularly. The problem is that they are known for being short strikers. In other words, they will hit your line and take your bait very often without being hooked because you didn’t even notice they were there. This is a common problem that makes it difficult for many anglers to catch walleye. However, the tips listed below will help you overcome these obstacles and have more success when you go walleye fishing.
Tips on How to Fish for Walleye
As mentioned above walleye are notorious for taking the bait and leaving you to wonder what happened. There are a couple things that you can do to prevent this from happening to you. Normally, the walleye virtually inhales the bait and surrounding water but if anything happens to spook the fish or interfere with this natural process he will not take the bait all the way. This means that you will get a very short strike that you can barely feel or he will move on without trying to take the bait. Your job is to find ways to prevent anything from interfering with this process so the walleye will completely take the bait and you will have more opportunities to catch more fish.
To accomplish this it is recommended that when trolling in choppy water you go with the waves because you need a little slack in your line when fishing for walleye. A very small amount of slack will help prevent the walleye from being scared away before you have the chance to catch him. It will also help you to know when you have a bite because the line will tighten. However, don’t leave too much slack or it will defeat the purpose and you will not have much luck.
