To expand their use, he is overseeing development of a practical, affordable safe room that would:. Falk expects to finish development in a year or two, and hopes to persuade stores in Tornado Alley to sell a complete kit of materials and instructions.

Shelter is the name of the game, says tornado expert Bluestein. If everyone hears about a tornado and gets in the car to try to outrun it, they will get caught in traffic, and they are going to get hurt. Post navigation. Tornado damage in Louisville, Miss. As many as 41 tornadoes struck the U. Credit: Mississippi National Guard. April 27, tornado-producing storms seen from space Time-lapse video of the weather system that spawned tornadoes in seven central and southern U.

Those explosions of white show water rising rapidly, powered by convection, marking tornado tops on this turbulent spring day.

Credit: National Weather Service. Supercells form where warm, moist air from the Gulf of Mexico meets cool, dry air from the west. The sun warms the moist, air, which rises due to convection, breaking through the cap and releasing latent heat that powers the updraft, the thunderstorm and tornadoes.

The Why Files. A tornado forms when 1. Humid air is trapped beneath cold, dry air; 2. Lower air rises and expands toward the reduced pressure aloft, punching a hole in the cap; 4.

Moisture condenses, releasing latent heat which warms the air, causing it to rise by convection at up to mph. The cloud has now formed a thunderstorm; 5. A tornado may form below the mesocyclone. As the spinning air column narrows, it rotates faster and the funnel cloud extends higher into the storm. Adaptation of tornado diagram from Shutterstock.

This was one of the strongest twisters since and one of only nine to reach EF5 between and in North America. Notice the large cloud of flying debris at the base.

This mass of dirt, rocks and building parts is a major cause of injury in tornadoes. We have had only one dinky and I mean real small category 1 hurricane on the upper Texas coast.

It caused waves less than 15 feet high, a very modest surge of less than 5 feet, and produced only modest localized wind damage. The end is near; the official end of hurricane season is just a few weeks away November So what typically is left of hurricane season; where do storms and hurricanes form this late in the season?

Well, the climatology of the tropics is a very strong indicator of what to expect and November climatology see graphic below points to the west and southwest Caribbean Sea, along with random, renegade storms forming in the southwest and subtropical north Atlantic typically moving rapidly northeast away from land -- minus Bermuda.

Why, you ask, do they tend to cluster along the east coast of Central America in November? The answer is simple: The monsoon trough of low pressure that haunts the tropical Eastern Pacific in summer retreats toward land and northwest South America before it dissipates in December and re-forms as a separate, unique monsoon heat low in Brazil's Amazon in Southern Hemisphere summer beginning in late December.

But, before the monsoon trough dissipates, it can become a brief stationary low pressure feature in the southwest Caribbean Sea and bring heavy rains to Honduras, Nicaragua, Costa Rica and Panama before it dissipates. In some rare cases -- maybe once in four years, this persistent low will briefly manage to organize enough to become a named storm; hence, we see the cluster of origins there when we look back in time.

The origin dots include some northward drift away from the monsoon trough origin prior to getting a name. These tropical cyclones rarely become hurricanes; most are weak or moderate tropical storms and most simply drift onshore Central American and dissipate.

Rarely, one gets captured by a mid-latitude trough of low pressure and skirts by or over Florida or moves northeast across the Bahamas on the way to becoming a non-tropical low. How did Hurricane Katrina form? How can you monitor storms? DOW documented several tornadoes later that day. The balloons drifted west from Africa over the Atlantic Ocean at heights of around 65,, feet.

Each one carried a gondola filled with instrument packages. Scientists on the ground sent signals to the gondola when they wanted it to drop an instrument package into a storm. The instrument package, which radioed back information about temperature, relative humidity, and wind, helped researchers determine which storms could strengthen into hurricanes. The driftsondes provided unique data on the atmospheric conditions over the tropical Atlantic, a remote area where hurricanes develop.

How does a Blizzard form? Warm front and cold front meet 2. Heavy nimbostratus clouds snow clouds develop 3. Come up with your own question and then answer it. The remainder of the period on both days was spent on the GIZMO site, completing the handouts for the water cycle. If you were absent, go online to www. Use your username and password to sign in.

This is the do now. Complete by using the words at the top of the list to fill in the blanks. Students will be able to: use information from textbook, virtual activities, and classroom discussions to -cite evidence of the cycling of water between the hydrosphere and atmosphere. Students submitted their scientist cards. The do now was a cloze activity that can be found at the top of this blog.

Students also received HL 11, which can be found at the top of this blog. There will also be a notebook check tomorrow. Students viewed a BrainPop movie on the water cycle. The respective do nows were: Wednesday - draw the water cycle scheme.

Thursday - Quick write - Why is the water cycle necessary for life on earth? Friday - use your assigned vocabulary word and write a sentence using the word. Students submitted HL 10 and reviewed it on Wednesday. For the remainder of Wednesday, and on Thursday and Friday, students researched their assigned scientist and used Comic Life to make a word wall poster of a assigned vocabulary word. The technology project scientist baseball card is due on Monday, 11 October, and the instructions can be found at the top of this blog.
