Hello, my class has been exploring weather and how it works. Me and my partner got assigned rain and rainbows so we had to find out how it happens, what conditions it needs to be in and make a presentation about our weather. did you know a rainbow is a full circle? Thanks for reading.

Yesterday we did weather presentations and our weather was lightning and we did a epic poster which we thing was great in our opinion, so here are some of the facts we put on it.

lightning is formed by tiny pieces of ice in a storm cloud that rub together that make a static charge which, when big enough will come down and strike the earth. Lightning can strike the earth millions of times per day with a charge that can be as powerful as 125 volts at speeds of up to 270,000mph.

Different types of lightning include sheet lightning and fork lightning. Sheet lightning takes up the whole sky in that area for a brief second whereas fork lightning shoots down to the ground in bolts or jagged lines.

In school we have started a new topic weather and natural disasters, but at the moment we are just studying weather. Me and my partner were looking at wind, here are some types of winds, calm winds, light air, light breeze moderate breeze and fresh breeze, moving on to strong winds,  moderate gale, fresh gale, strong gale, whole gale, storm and then hurricane.

what is wind is the movement of air from a high pressure area to a low pressure area.

Hailstones are formed by layers of water attaching and freezing in a large cloud.  The biggest cloud of all is cumulonimbus which was really devastating as there was enormous hailstones the hailstone size went from 5mm to 200mm!  Hailstones fall so quickly they don’t have a chance to melt. Hailstones are actually more common in summer because there is more energy available at warmer times of the year. Warmer weather might actually result in a stronger updraft, an updraft is an up current of air. So the water rises up and freezes so that’s how we get more hail stones in summer.

Tornadoes are among the most violent storms on earth due to the damage it can cause to people and buildings.

How tornadoes are caused?

the hot weather super heats the ground and it causes the heat to rise. When the hot are meets cold air that causes storm clouds. This can cause thunder, lightning and rain it can also cause an air explosion. That starts the wind turning. Then it forms into a funnel and below the storm clouds is a Tornadoes.

Hurricanes are powerful storms and violent winds that form over water.

Hurricanes are a tropical storm that form in the Atlantic ocean with wind speeds of at least 119 km (74 miles) per hour.

It’s only when they move over land that their power can be seen much more clearly.

Hurricanes have 3 main parts, the calm eye in the center, the eye wall where the wind and rain are the strongest and then the rain bands which spins out from the center. That gives the storm it’s size.

Hurricanes with wind moving faster than race cars can tear down houses and lift up heavy vehicles often destroying everything in there path.
