*****If you are teaching the formation of a hurricane soon here is how I do it. #geographyteacher #geography. *****How I explain the formation of a hurricane – The Geographical Palimpsest. Step One – A Fertile Question It’s only in the last couple of years that I have finally arrived at the lesson on hurricane formation that I am happy to deliver.
Sure, cross sections where students can identify the features and the pre-requisites for their formation are fine, but I wanted to delve deeper. I want students to know the genesis of a hurricane from its humble beginnings as a series of small thunderstorms in equatorial Africa to the phenomenal hurricanes that news stations are so happy to send reporters out in to. To begin, I ask what Mark Enser would term a fertile question – ‘Why is the United States interested in thunderstorms in Africa?’ Step Two – Planning the Page Again, I would always suggest using a student exercise book to plan out drawings and explanations.
Step Three – Planning Stages I would draw the birds-eye view first then follow this with the cross-sectional view. Step 4 – Thunderstorms over Africa The key points I would want students to know are: *****Why do Tropical Cyclones maintain intensity or even strengthen slightly inland over the Everglades?

The population of Puerto Rico stood at 3.2 million in 2018, its lowest point since 1979 and down sharply from 2017, when hurricanes Maria and Irma hit the island, according to a Pew Research Center analysis of U.S.
Census Bureau data. The 3.9% decline in 2018 represents the largest year-to-year drop since 1950, the first year for which annual data is available. The number of people in Puerto Rico has dropped by 632,000 since its peak in 2004. Even before the hurricanes hit, Puerto Rico’s population was expected to drop to less than 3 million by 2025, according to projections published in 2017.
*****Tropical cyclone wind speed relative to ocean sea surface temperature. Very warm ocean water is a necessary, but not sufficient, criterion for forming the strongest tropical cyclones such as Category 5 hurricanes and super typh. Twitter. Hurricanes! Almost all of those that hit the USA develop in the same spot off of the West coast of Africa. *****Are hurricanes getting worse? As Florence barrels toward the US east coast, two more hurricanes follow closely behind.
The 2018 hurricane season has suddenly erupted, a year after the 2017 season ruined thousands of lives. While 2018 was expected to be “below normal”, there is a great deal of uncertainty. We won’t know the full scale of the damage until the season is over, but longer term trends indicate a worsening of the length and intensity of Atlantic storms.
Since 1970, there has been an average of six Atlantic hurricanes per year. *****Simulation: Storm surge will be a huge factor for Hurricane #Florence Check out what it might look like with @TWCErikaNavarro:… This kind of coastal development never made sense.

Stronger storms mean new 'category six' scale may be needed.
The increasing strength, intensity and duration of tropical cyclones has climate scientists questioning whether a new classification needs to be created: a category-six storm.
The Saffir-Simpson hurricane wind scale currently runs in severity from one to five, with five describing near-total destruction. But climate scientists meeting at a conference in the New Zealand city of Wellington have floated the idea of creating a category six to reflect the increasing severity of tropical cyclones in the wake of warming sea temperatures and climate change. Climatologist Michael Mann, the director of the Earth system science center at Penn State University said the current scale could be viewed as increasingly outdated. I ended up putting all of this into a video, describing how this phenomenon happens. Incredible loop of Cyclone Kelvin making landfall in Australia AND THEN forming an eye.…

Image copyright Getty Images US employment fell in September for the first time since 2010 as hurricanes Harvey and Irma took their toll on the jobs market.
The Labor Department said 33,000 jobs were lost amid a record drop in employment in the leisure and hospitality sector. It blamed the two storms, which struck Texas and Florida in late August and early September, for the slide. Economists had expected a rise of 90,000 jobs last month. However, Harvey and Irma did not affect the unemployment rate, which slipped to 4.2% - the lowest since February 2001.
The US Labor Department uses separate surveys to capture payrolls data and the unemployment rate.
