VISMAR+PROJECT

This is my part of the project about what is weather and how it is caused.
2.There are a lot of ways that temperature changes.One way it changes is the climate in each country or state. Another way, if a hot and cold whether combines it produces rain to fall down. Temperatures from the past left their traces in three rings, coral reef and ice cores. There are even more like the clouds. They made of gas and vaporize into snow or rain. The way hail is created is by thunderstorm and the updraft in the air and the downdraft in the air. Super cells are one of the main things that form tornadoes. Dust storms are created by winds moving across an arid region. Many times a strong dry cold front is the mechanism that creates the dust or sand storm. As strong winds move across an arid landscape, sand or dirt is picked up from the ground. Sometimes the lighter dust particles can be lifted up to 20,000 feet high into the atmosphere. A classic example of this is a sand and dust storm that develops over the Sahara desert. Easterly winds may carry the dust particles across the Atlantic ocean to the Caribbean Islands or Florida. Severe sand and dust storms can obscure visibility to zero and last for days.

4.Wind is the motion of air in the atmosphere. Wind is caused by an imbalance of heating from the sun. The uneven heat Lightning is simply a discharge of electricity in the atmosphere. Sleet is transparent frozen raindrops. Sleet or ice pellets are created when snow falls into air above freezing and melts into rain drops. If another below freezing layer below the warm air is of sufficient depth, the rain drops freeze into balls of ice or ice pellets. Any significant amount of sleet is farily rare. This is due to the fact that there needs to be just the right conditons to get a perfect layer of warm air in between the layers of cold air. There have been cases of storms producing several inches of sleet. A mix of snow and sleet and sleet and rain is more common. Lightning is simply a discharge of electricity in the atmosphere.
