Hurricane Ernesto

Hurricane Ernesto was the costliest tropical cyclone of the 2006 Atlantic hurricane season. As the fist hurricane of the season, Ernesto developed from a tropical wave on August 24th in the eastern Caribbean Sea. Ernesto first hit the northern Caribbean reaching minimal hurricane status near Haiti before weakening and moving across eastern Cuba as a tropical storm. Ernesto moved across Florida as a weak tropical storm. After turning to the northeast, it re-intensified and made landfall on August 31 on the coast of North Carolina. Eleven people were killed and Damage in the United States was estimated at $500 million.

Hurricane Rita

In 2005, Hurricane Rita was the fourth-most intense Atlantic hurricane ever recorded and the most intense tropical cyclone ever observed in the Gulf of Mexico. A Category 3 hurricane with a wind speed of 120 mph.

Post #11 Hurricane Charley

This hurricane was generated in less than a weeks time in the tropical Atlantic. It contained winds over 150 mph, and existed from August 9 to August 15, 2004. It spawned in the east of the Windward Islands on the 9th of August and traveled speedily to the west across the Caribbean. As it was on its way to Jamaica, it built up and destroyed some parts of the island on 11th August, and also went through the Cayman Islands. On 12th August, it went over Cuba, which is in the west of Havana. While it was heading towards the northeast, it strengthened up speedily in just a few hours, and eventually made landfall near Port Charlotte, Florida, where it destroyed life and property to a great extent. Hurricane Charley was a fast-moving tropical storm which caused destruction by its strong winds, rather than heavy rainfall. It later destroyed property while passing near Orlando and Daytona Beach. On 14th August, it made the next landfall in a region near North Myrtle Beach, South Carolina. By the time the hurricane dissipated near Cape Cod, Massachusetts on 15th August, it had made serious damage worth $14 billion, with approximately 15 deaths to its credit.

Post #10 Weather Balloons

WEATHER BALLOONS carry an instrument called "Radio-sonde" which measures temperature, pressure, and humidity at different altitudes in the atmosphere. Special recording equipment in the balloons converts readings from these instruments into electrical impulses and transmits the impulses to earth. The balloons are tracked with radar to find wind speed and direction. Eventually the balloon bursts, and the instrument floats back to the ground by parachute.

A tornado forms when the wind coming into a storm starts to swirl and form a funnel. The air in the funnel spins faster and faster and creates a very low pressure area, which sucks more air and possible objects into the funnel. The severe thunderstorms that eventually cause tornadoes, are caused by cold polar are mixing with warm tropical air.

This is a simple barometer. A barometer measures atmospheric pressure. It can messure the pressure exerted by the atmosphere by either using air mercury or water. The pressure tendancies showed by the barometer can predict short term changes in the weather.

hurricane katrina first hit land on august 23, 2005 and was only a catagory 1, causing a small number of deaths and minor flooding. but on the 29th it hit land a second time and was a catagory 3. this effected humans by causeing thouands of deaths and billions of dollars in property damage

YAYA CYCLONE LARRY

Tropical Cyclone Larry formed off the northeastern coast of Australia on March 18, 2006. The cyclone gained power rapidly and came ashore on Queensland’s eastern coastline, where it hammered beaches with heavy surf, tore roofs off buildings, and perhaps most destructively, flattened trees in banana plantations over a wide area. The Australian Broadcasting Corporation reported early estimates that as much as 90 percent of the Australian banana crop may have been lost in this single storm. Since many trees have been destroyed, it may be many years before the banana industry recovers.

YAYA RAIN GAUGE

a rain gauge is a type of instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation. Liquid is mesured in milameters

Hurricane Alex

hurricane alex was a rare june hurricane. the hurricane struck

near Soto la Marina, Mexico on june 30th as a category 2 hurricane. Hurricane Alex caused the death of 51 people.

YAYA ARETE

An arete is a thin, almost knife-like, ridge of rock which is typically formed when two glaciers erode parallel u-shaped valleys. The arete is a thin ridge of rock that is left separating the two valleys.

Post #11 Violent Weather

The image on the left is an image of Hurricane Mitch, this hurricane was the most powerful of the 1998 hurricane season. It had sustained winds of over 180m/ph (285km/ph) . Mitch formed in the carribean sea on October 22nd, it rapidly changed to category 5 status on the Saffier-Simpson hurrican scale. It hit Honduras as a minimal hurricane, drifted through Central America, reformed in the Bay Campeche and ultimately struck Florida as a strong tropical storm. Due to the slow movement of the hurricane it caused historical rainfall in the places it afflicted and caused roughly 11,000 and 11,000 missing and finally reaching a deathtoll to 19,325 due to the surge and massive flooding that hit the places mitch afflicted.

That's unfortunate ...

This is a satellite image of hurricane Denis, Emiy, Katrina, Rita and Wilma. They all happened in 2005. They made landfall all in the Gulf of Mexico causing the US $180 billion in damage.

What is happening is that a tornado is occuring. Tornado's are formed by warm tropical air meeting with the cold air, this is caused by the warm air rising. This tornado occured in Pennsylvania, it happened in the later part of the afternoon around 3:45pm. Not very many people were affected because it did not hit the city.

This is a tornado that occured in 0klahoma in 2007, it struck the town of Minco and devistated the landscape. Whipping out precious farmland and economic buildings.

YAYA MESA

An elevated area of land with a flat top and sides that are usually steep cliffs. It takes its name from its characteristic table-top shape. It is a characteristic landform of arid environments.

Tornado Outbreak

On May 4th 2007, a Tornado outbreak started, affecting portions of the Central United States. 95% of the city of Greensburg in Kiowa County was destroyed by an EF5 Tornado. Killing about 13 people and injuring about 60 more. The weather outbreak can be traced back to a powerful, slow-moving low pressure area with a warm front to the north over Nebraska and Missouri. The duration of the tornado lasted about 56 hours and 9 mintues. The estimated cost of damageswere in the 250 millions.

Hurricane Gustav

Hurricane Gustav was the second most destructive hurricane of the 2008 Atlantic hurricane season. Caused serious damage and casualties in Haiti, the u.s and the Dominican Republic. It caused at least $6.6 billion in damages. Gustav triggered the largest evacuation in United States history.

In July 2010, a F3 tornado ripped through Saskatchewan. It made a path half a kilometre wide and at least 45 kilometres long. Wind speeds reached between 253 and 331 kph. No one was seriously injured, but 15 homes were destroyed and other buildings were badly damaged.

This is an image of a rain guage. It catches falling rain and scientists use the collected rain to determine daily, monthly and annual rainfall in a specific area.

Post #10 Atmosphere

The image on the left is an image of a barometer. A barometer is used for the measuring the weight of atmospheric pressure or the weight of the air. This instrument can fairly accurately predict a change in weather and can meausre how much the weather has changed in recent days. The SI unit is called "Pascals", these measure one ''newton'' per square meter.

Hurricane Igor! :(

Hurricane Igor: Category 4 September 2010

Hurricane Igor was the strongest recorded Hurricane to hit the Canadian East Coast island of Newfoundland. It also affected the Carribean, Eastern USA, and Bermuda.

It caused 4 direct Fatalities, over $200 million dollars worth of damage and had severe flooding.

In August 2005, Hurricane Katrina struck the southern coast of Florida, and then proceeded on its way to New Orlenas, Louisiana. Almost 2000 people were killed and an estimated 80 billion dollars in damage were made.

Wa-wa-wa-wind Vane.

Wind Vanes are used to show which way the wind is blowing. Normally they are placed at a higher altitude and in the open so that the wind hits it.

roche moutonnee is a rock formation which has been eroded down by a passing glacier, giving it a rough side, and a polished side.

a anemometer is a common wheather station insrument measureing wind speeds.

This is a Barometer and it is used to measure the air pressurel. It is meausred in kilopascals and millibars.

Esker

This is a picture of an Esker. It was formed by the deposition of a stream under a glacier. It is a continental glaciation feature.

Hoodoo

This Hoodoo was formed when wind blew sand which eventually eroded the base of the rock through the process of abrasion. A Hoodoo is a erosional feature.

This is a sea breeze explanation of how the winds work with the ocean currents.

Barometer

A barometer measures atmospheric pressure, which helps to predict clear or rainy weather. The air presses down on the mercury's exposed surface and pushes it up into the tube. The higher the mercury level, the greater the air pressure. The units of air pressure were measured in millimters of the mercury.

Seabreeze or onshore breeze is wind from the sea that develops over land near coasts. Formed by increased temperature differences between the land and the water!

Sea-Land Breeze

Land Breeze: is a type of wind that blows from the land to the ocean, land breezes usually occur at night.

Sea Breeze: is a wind from the sea that develops over land near coast, it is formed by increasing temperature differences between the land ad water which create a pressure minimum over the land due to its relative warmth and forces higher pressure, cooler air from the sea to move inland.

Sea Breeze

Air always goes from HIGH to LOW pressure

Weather Vane

This is a picture of a weather vane. It is used by meteoroligists to find out the wind direction. It uses cardinal direction as measurement.

Post # 10 Craig and Tail

There is an outcrop of rock (crag) and it is followed by a tail of deposited debris from a glacier. This is formed by deposition and it is a continental feature.

Post #8 Sand Dunes

**Sand dunes are created throgh the aeolian process. This process occurs because of obstructions in the desert that are covered with sand. Sand dunes are depositional.

Crag and Tail

A crag and tail is a larger rock mass than a roche moutonnee. Like a roche moutonnee, it is formed from a section of rock that was more resistant than its surrounding. the resistant rock, the bed rock was protected from the erosional power of the glacier. this is formed by deposition and it is a continental feature.

Wadi

A wadi is a gully, streambed, or vally which is characterized by being extremly dry. Many wadis flood during the rainy season. They are formed by seasonal or intermittent rains but are dry most of the year. The bottom of a wadi is often coverd in sand and coarse rock, and the sides may by steep and made from sandstone or similar materials. Wadi's can be very dangerous in the rainy season. It is also depositional.

Stalagmite

Stalagmites are formed by water dripping or flowing from fractures on the ceiling of a cave. In caves, stalagmites grow rather slowly. While in artifical tunnels and basement they grow much faster. dripping waterfalls down on the floor of the cave it forms the stalagmites, which grow up vertically from the cave floor. Stalagmites resemble piled-up plates.

Arete

An arete is shartp ridge created from glacial erosion on either side. There are often cirques on each side. Typically formed when two glaciers erode parrallel U-shaped valleys.

Mesa

This is an image of a mesa, a mesa is a table shaped mountain with a flat top and steep sides. A mesa is formed by weathering and erosion of layered rock that have been uplifted by tectonic activty.

YAYA STALACTITE

Stalactites are formed by the deposition of calcium carbonate and other minerals, which is precipitated from mineralized water solutions. They form coming down from the ceiling of the limestone underground cave. These caves are great places to explore.

This is an image of a "crag and tail". There is an outcrop of rock (crag) and it is followed by a tail of deposited debris from a glacier. This is formed by deposition and it is a continental feature.

Cirques

Cirques are formed by glacier ice eroding the ground into a bowl like feature.
