Hurricanes Classification
- Hurricane ‘Dorian’ is on track to make landfall in Florida as extremely dangerous ‘Category 4’ storm.
- Meteorologists use the ‘Saffir-Simpson Hurricane Wind Scale’ to measure a hurricane's strength.
- It is a 1 to 5 rating scale based on a hurricane's sustained wind speed.
- This scale estimates potential property damage.
- Category 3 and higher are considered as major hurricanes because of their potential for significant loss of life and damage.
- Category 1 and 2 storms are still dangerous, require preventative measures.
- In the western North Pacific, the term "Super typhoon" is used for tropical cyclones with sustained winds exceeding 150 mph.

- However this scale only takes into account a storm’s maximum windspeed and disregard other threats like expected rainfall or storm surge.
- An alternative to the Saffir-Simpson Scale is AccuWeather’s “Real Impact Scale”.
- This takes other metrics besides wind speed into account.
Evolution of Jupiter
- ‘Juno’, the NASA probe orbiting Jupiter, has been sending information that gives scientists new insights into the evolution and structure of the planet.
- A new study suggests that 4.5 billion years ago, Jupiter received a massive whack from a planet still being formed and swallowed it.
- Another study looks at the reasons why the “stripes” on Jupiter do not run deep into its surface.
- Information sent by Juno shows that Jupiter’s core is not mainly ice and rock as previously thought.
- It is a “fuzzy core” that includes lighter elements like helium and hydrogen.
- Scientists suggest that it could be explained by a head-on collision with a still-forming planet about 10 times the size of Earth.
- Magnetic fields can make fluids that conduct electricity (like Jupiter’s atmosphere) behave more like honey than water.
- Deeper into the planet, where the pressure is higher, the atmosphere becomes more conducting.
- It is more strongly influenced by the planetary magnetic field.
