Problem Based Learning Model

  1. Read and analyze the scenario and situation - Hurricane

Category 5 Hurricanes have caused human and property damage in the United States. Several hurricanes made landfall in 2007 in both Atlantic and Pacific coastal areas at the same time. Tracking these storms have been documented as early as the 1900 when a major storms nearly destroyed all of Galveston

  1. List your personal understanding, ideas or hunches

    Juana Martinez

    Hurricanes have a powerful impact in the United States and cause major destruction of people and property. Here in the valley we have been spared major storms. The last one that made landfall was Hurricane Dolly which brought major flooding to our area.


    Michelle Salazar

    We live in an area where hurricanes are likely to hit. The area we live in is close to the Gulf of Mexico. Major hurricanes hit here every 3-4 years. I have several questions about hurricanes I would like to find out about.

    Claudia Perez

    I haven’t experienced too many hurricanes but I do know it is scary to know that your home can be destroyed in a matter of hours. When I was a kid, I remember having to leave my home to take refuge in a school that was being used as a shelter. There were a lot of other families there and each just as scared as we were. I remember my mom trying to keep us calm, while my dad just paced up and down a hallway. I can’t forget the sound of the rain against the roof and the hard winds that never seemed to stop. I also remember weather reports on TV or the radio. As a grown up, experiencing hurricanes is a whole new kind of scary. Now I’m the one trying to keep my kids calm, but preparing for the worst.


    Maria Izquierdo

    The subject about hurricanes has always been an interesting. Much knowledge about hurricanes has been learning throughout my high school and college years. I remember that my science teacher would always tell to pick a subject to present, and I would always pick on hurricanes. I always became interested due to the fact that we live in an area, that every year we are prone to become affected by them. How serious is this? Well, to me this is very serious because hurricane season starts June 1 and ends November 30, every single year. This means that from this time to this time, we can be hit by a hurricane at any time whether it’s a tropical storm, up to category 5 hurricanes. So the valley is very sensitive to hurricanes. During the 1900’s when the Galveston hurricane hit, the meteorologist did not have the technology or resources that they now have to help predict where, how long, when the hurricane will hit a place. I think this play a major role in the Galveston hurricane.


    Leticia Calderon

    Hurricanes cause destruction to people’s property. In the last hurricane (Dolly) we experienced a great deal of flooding to area. The floods caused damage to local farm lands which affect our produce prices. Hurricanes also impact the work force and higher prices for everything from gas to food. Due to the extensive flooding, a major problem with mosquitos also occurs.

  2. List what is known

Juana Martinez

What I know?

  • There is a hurricane season every year that runs from June through November.

I know this because the meteorologist track the Pacific and Atlantic very careful during this time for any storms that may developed.

  • Hurricanes have different categories according to the wind strength.

I know this because I have lived through several tropical storms that have been categorized as low as tropical depression to hurricanes like Alicia that made landfall through Houston


Michelle Salazar

What I know?

I know that hurricane start as a tropical wave and can turn into hurricanes within days.

I know this because I watch the weather channel when a tropical storm is on its way.

What I know?

Hurricanes are unpredictable and can increase in strength within hours.

I have seen how a hurricane headed our way changes path within hours of predicted landfall.


Claudia Perez

Hurricanes :

  • cause millions of dollars in damage due to high winds and heavy rain

  • cause mass flooding of homes and roads

  • can be unpredictable

  • can have winds of 100 mph or more

  • travel in spiral formation and the center of the storm is the most dangerous

  • hit coastal areas

  • form in the ocean

  • cause fear and apprehension in coastal areas take down power lines and affect water drainage systems

How do I know it

I haven’t experienced too many hurricanes but I do know it is scary to know that your home can be destroyed in a matter of hours. When I was a kid, I remember having to leave my home to take refuge in a school that was being used as a shelter. There were a lot of other families there and each just as scared as we were.

Maria Izquierdo

  • It is the most Catastrophic hurricane to hit the state of Texas.

  • It killed thousands of people.

  • It hit as a category 4 hurricanes.

  • It hit the city of Galveston TX.

  • Destroy most of the city

  • Flooded the city

  • People were left without light for days for those who did not evacuated the city.

  • cost the city of Galveston too much money in repairs

  • cause health problems, because of water contamination, due to bodies floating in the water




Leticia Calderon

They only occur during a set season.

Other climate changes the severity and number of hurricanes.



They are unpredictable. We don’t know the effects of the impact or its exact place it will land until it hits land.

  1. Develop a problem statement – Hurricane Scenario

Every hurricane season that runs from June to late November, we watch the weather closely and track tropical storms that might affect the valley. Hurricanes can come into our southern coast and cause major destruction just like the Hurricane that made landfall in the 1900’s in Galveston. Research shows that these storms are becoming more intense and more frequent. In 2007, two category hurricanes made landfall in the Pacific and Atlantic Coast at the same time. We need to learn about these powerful storms and how to keep them from causing so much destruction of lives and properties.

  1. Gather Information

What did we find to support our problem statement?

Juana Martinez

  • How can we predict the next major storm that will affect our area?

Around April of each year, meteorologist starts talking about how many storms are predicted for the season and how many of them are expected to make landfall. Now scientist can even predict the number of named storms and how intense they will be.

Scientist can predict approximate wind speeds and intensity for sustained winds. This is calculated by comparing to past seasons. The sustained wind speed follows the Poisson distribution with some accuracy. The storms are predicted based on the activity from the past years and current measures of factors in the climate. They is some discrepancies in the prediction so In reality there is no precise way to predict a hurricane. Basically, meteorologists use the data such a water temperature, wind patterns, jet stream, humidity levels to name some. The use this weather conditions to determine if the condition is favorable for an active hurricane season.

Michelle Salazar

How are hurricane categorized?

You may have heard the Saffir-Simpson hurricane scale referred to in a weather report, or seen it mentioned in an article, in relation to a hurricane. For example: “Hurricane (blank) is now a Category 1 storm…”

The National Hurricane Center explains it this way:
It’s a way to categorize the storm based on the hurricane’s intensity at an indicated time.
All hurricanes are dangerous, but some are more so than others. The way storm surge, wind and other factors combine determines the hurricane’s destructive power. To make comparisons easier and to make the predicted hazards of approaching hurricanes clearer to emergency managers, National Oceanic and Atmospheric Administration's hurricane forecasters use a disaster-potential scale, which assigns storms to five categories. This can be used to give an estimate of the potential property damage and flooding expected along the coast with a hurricane.

The scale was formulated in 1969 by Herbert Saffir, a consulting engineer, and Dr. Bob Simpson, director of the National Hurricane Center. The World Meteorological Organization was preparing a report on structural damage to dwellings due to windstorms, and Dr. Simpson added information about storm surge heights that accompany hurricanes in each category.



Here is general information about the five hurricane categories, wind speeds, and effects:

Category 1: Winds 74-95 mph - Damaging winds are expected.

Effects: No real damage to building structures. Damage primarly to unanchored mobile homes, shrubbery, and trees. Also, some coastal road flooding and minor pier damage.



Category 2: Winds 96-110 mph - Very strong winds will produce widespread damage.

Effects: Some roofing material, door, and window damage to buildings. Considerable damage to vegetation, mobile homes, and piers. Coastal and low-lying escape routes flood 2-4 hours before arrival of center. Small craft in unprotected anchorages break moorings.



Category 3: Winds 111-130 mph - Dangerous winds will cause extensive damage.

Effects: Some structural damage to small residences and utility buildings with a minor amount of curtainwall failures. Mobile homes are destroyed. Flooding near the coast destroys smaller structures with larger structures damaged by floating debris. Terrain continuously lower than 5 feet ASL may be flooded inland 8 miles or more.



Category 4: Winds 131-155 mph - Extremely dangerous winds causing devastating damage are expected.

Effects: More extensive curtainwall failures with some complete roof strucutre failure on small residences. Major erosion of beach. Major damage to lower floors of structures near the shore. Terrain continuously lower than 10 feet ASL may be flooded requiring massive evacuation of residential areas inland as far as 6 miles.

 

Example of Category 4 hurricane from space - Hurricane Luis, 1995:



Wikipedia information about Hurricane Luis: Hurricane Luis was a very large, very intense Category 4 Hurricane, formed August 27, 1995, as well as being among the most notable storms of 1995. Due to the severe damage and loss of life caused by Luis in the Lesser Antilles, the name was retired in the spring of 1996, and will never again be used for an Atlantic hurricane. It was replaced with "Lorenzo" in the 2001 season. Luis was the first L name to be retired since 1954, and was the first Atlantic hurricane name to be retired in three years since Hurricane Andrew in 1992. Source: Wikipedia - Hurricane Luis

Category 5: Winds greater than 155 mph - Catastrophic damage is expected.

Effects: Complete roof failure on many residences and industrial buildings. Some complete building failures with small utility buildings blown over or away. Major damage to lower floors of all structures located less than 15 feet ASL and within 500 yards of the shoreline. Massive evacuation of residential areas on low ground within 5 to 10 miles of the shoreline may be required.

National Hurricane Center: Saffir-Simpson Hurricane Scale

A revised version, called the Saffir-Simpson Hurricane Wind Scale (Experimental), is now available on the National Hurricane Center’s website. It has removed storm surge ranges, flooding impact and central pressure statements from the scale and only employs peak winds.

Here's the link: Saffir-Simpson Hurricane Wind Scale (Experimental), National Hurricane Center

How often do weather meteorologist tract the predicted paths?

UPDATE BY:Jim Williams..... The hurricane season has ended with 19 named storms of those seven became hurricanes. On my annual Hurricane season kickoff show I made my city and island picks for impacts from named storms which can be seen on my predictions page. Once again I did pretty good with 3 of my top 5 areas hit with the worst impact being on Great Exuma Isl Bahamas my #4 pick. The island was hit by Hurricane Irene with 120mph winds on Aug 24th causing extensive damage. This is why I always say that if your location is in my top 5 your chances of a significant impact are way above normal. On June 1st I stated that I felt South Florida would be impacted during the season. I was so confident of this prediction that I placed a bet that if the area was not impacted I would wear a costume of the viewers choice. After many emails were sent in, the number one choice was for me to wear a hot dog suit with sponge bob and tinker bell as close second's. South Florida was not impacted by a named storm in 2011 so I wore the hotdog suit on the November 30th end of season broadcast. Archive subscribers can watch the two hour show here .

The number of severe hurricanes has doubled worldwide even though the total number of hurricanes has dropped over the last 35 years, a new study finds.



The increase in major storms like Katrina coincides with a global increase of sea surface temperatures, which scientists say is an effect of global warming.

The possible relationship between global warming and hurricane strength has been a topic of controversy for years.

The new study supports another one released in July, in which climatologist Kerry Emanuel of the Massachusetts Institute of Technology showed for the first time that major storms in both the Atlantic and the Pacific since the 1970s have increased in duration and intensity by about 50 percent.

Global warming might not fuel more intense hurricanes in the Atlantic after all. Despite increasing ocean temperatures that feed the monstrous storms, climate change may also be ramping up the winds that choke off a hurricane’s development.

Maria Izquierdo

What are the steps meteorologists take when a hurricane approaches? What type of communication do cities have when they prepare for a hurricane?

There is a forecast process when it comes to the type of communication local cities have:



  • watches

  • warnings

  • forecasts

  • Analyses of hazardous weather conditions in the tropics.

The coordination falls into three categories:

  • 1st - Hurricane Hotline Coordination
    2nd - International Coordination
    3rd - Emergency Manager Coordination

  • National Weather Service (NWS) national centers, NWS forecast offices, NWS river forecast centers, and several Department of Defense installations.

  • INTERNATIONAL COORDINATION
    The TPC issues watches and warnings for the United States. However, the national weather services of the Caribbean countries, Central America, Mexico, Bermuda, and Canada
     

  • COORDINATION WITH EMERGENCY MANAGERS
    One way this occurs is through a briefing for federal, state, and local emergency managers held by the Hurricane Liaison Team (HLT) of the Federal Emergency Management Agency (FEMA)

  • Tools use

  1. Weather radio

  2. Radar

  3. sky warn

Here in the valley National Weather Service Weather Forecast Office of Brownsville, TX is in charge of the communication efforts in the valley

Event to Sphere interactions

E A


Hurricanes have strong winds but only for a short time during the storm however Hadley cells do exist in the atmosphere. Hurricanes are located in the troposphere layer of the atmosphere.

E H


Hurricanes affect the action of the waves during the storm. There is also mixing of the water as the result of the action of the waves but only about 100 feet down.

E L


Hurricanes will increase erosion of beaches. The rainfall can loosen the soil and cause mudslides.

E B


Hurricanes will have a major effect on bio domes and human lives.
