What causes hurricanes or tornadoes to begin spinning?
Hurricanes and tornadoes spin for different reasons. Hurricanes spin dues to the Coriolis effect, a consequence of the earth's spin. How it works is somewhat complicated, bu in essence the air flowing into a hurricane gets deflected, to the right if it is in the northern hemisphere and to the left in the southern hemisphere. This causes counterclockwise and clockwise rotation respectively. Tornadoes, by contrast, are too small for the Coriolis effect to have a significant influence. Tornadoes get their rotation from the parent thunderstorm, which has a rotating updraft called a mesocyclone. Wind shear, a difference in wind speed and direction with altitude essentially twists the updraft, causing it to start rotating.
How are tornadoes formed for third graders?
Tornadoes form from powerful, spinning thunderstorms called supercells. Sometimes some of the spinning air can start to squeeze tighter, which causes it to spin faster and stretch toward the ground. When it reaches the ground a tornado is born.
What is different about the places where hurricanes start and the places where tornadoes starts?
Hurricanes are tropical storm systems that form only over warn ocean water. Tornadoes are less limited. They usually form on land in temperate climates, but they can occur on water (in which case they are called waterspouts) and in tropical regions.
Do tornadoes have weaker winds than hurricanes?
No, tornadoes can produce winds faster than in any hurricane. There is actually a substantial amount of overlap between hurricane and tornado winds. Winds for an EF0 tornado start at 65 mph and winds in the strongest tornadoes have been recorded at 302 mph. Hurricane force winds start at 74 mph. Hurricanes have had sustained winds as fast as 190 mph with gusts recorded up to 253 mph.

Why do tornadoes show up during hurricanes?
Hurricanes are enormous convective systems that produce thunderstorms. Because of friction, low-level wind speeds in a hurricane are slower than those in the higher levels. Such a condition is called wind shear. In some cases, this can cause some of the thunderstorms in the storm bands of a hurricane to start rotating. This rotation can then lead to the formation of tornadoes.
What causes a tornado simple answers?
In very simple terms, tornadoes form when thunderstorms start to spin when they run into winds blowing in different directions. The spinning air in the storm can then get squeezed tighter, causing it to spin faster and reach down to the ground to become a tornado.
Where do hurricanes start mostly?
All hurricanes start over the warm tropical oceans.
When did the harricane start?
how did hurricanes start? For my whole life I was wondering how hurricanes start but noone has found an answer so please tell me how it started.
What his stronger winds f5 tornadoes or category 5 hurricanes?
An F5 tornado has stronger winds. Category 5 winds start at 157 mph. On the original F scale F5 winds were estimated to start at 261 mph, but scientists now thing this estimate was too high, and have adjusted it to over 200 mph. At least one F5 tornado is known to have produced winds over 300 mph and others are also suspected to have done so.
How do hurricanes form tornadoes?
When a hurricane makes landfall it weakens rapidly, with the winds at lower levels weakening faster than those at upper levels. This difference in wind speed creates wind shear, which can cause the thunderstorms in the rain bands of a hurricane to start rotating. This rotating can then tighten and intensify to form tornadoes.
During what season do tornadoes occur?
Tornadoes usually occur in spring and early summer while hurricanes usually occur in summer and early fall. However, tornadoes can occur at any time of year, and out of season hurricanes have occurred as well.
