Tornado



A tornado is a funnel-shaped wind vortex that formed in or on the cloud base and extends cumullusnimbus like proboscis to touch the ground. At the end surrounded by dust, water, or debris (depending on where the tornado formed) that come round. Color is affected by the tornado formation. For example, if a tornado is formed in the desert region is a golden brown color and the edges surrounded by dust and sand.
The word tornado taken from the Spanish "tronada" which means lightning storm. Another version says the word tornado comes from the Latin "tronare" which means to turn. There is also a saying that the word tornado comes from a combination of both. Meanwhile, another term for a tornado is "twister".
Very large pressure difference in the areas of local scale occurred under or near the cumullusnimbus cloud causes the formation of a tornado. In the process often begins with the appearance of funnel-shaped cloud vortex (funnel cloud). This causes a funnel cloud is often regarded as a tornado. Funnel cloud is a manifestation of the condensation funnel, without any wind on the surface. While a tornado is a vortex of strong winds. Water vapor that condenses causing a tornado funnel cloud looks like.
Tornadoes frequently reported appear to form a single vortex. Besides being a single vortex, a tornado also appeared with the same two large whirlpool better known as the twin vortex tornado. Sometimes, also comes with a large whirlpool surrounded by 2 (or even more) smaller vortex. Small vortex tornado is called a satellite.
With the wind swirling speed between 40 mph to 110 mph and range up to 250 feet (of about 75 m), is clearly damaging tornadoes. Moreover, a tornado can move up to miles and miles away. Whatever its path would be damaged and destroyed. Several tornadoes have some turbulence speeds up to 300 mph, range up to 4 km, and moved up to 219 miles. Scientists classify tornadoes based on damage caused. There are 3 types of scale used to classify tornadoes. There Fujita Scale (F) and Enhanced Fujita Scale (EF) made by Dr. T. Theodore Fujita. Scale for the weakest tornadoes are F0 and EF0, while for the strongest tornado F5 and EF5. Weakest tornado can damage trees, whereas the strongest can destroy homes and even permanent damage to a skyscraper. Similar scale is the Torro Scale with a longer range. T0 to T11 tornadoes for the weakest and the strongest tornadoes. Torro scale created by the Tornado and Storm Research Organization.
Tornadoes can occur anywhere except in Antarctica. Greatest frequency is in Tornado Alley, United States. While the smallest frequency in the tropics.

Waterspout



Waterspout is a tornado is relatively small. Usually formed in water. Twister speed between 60 to 90 km / h and lasted for 5 to 10 minutes. Though formed in the water, waterspout could move up to the land and destroy everything in its path. Waterspout usually accompanied by a fairly heavy rain. In fact, often accompanied by ice. This phenomenon often occurs in tropical regions.

Valentine's Day

My inside all turn to ash (so slow)
And blew away as I collapse (so cold)
A black wind took them away (from sight)
And held the darkness overday (that night)

And the clouds above move closer
Looking so dissatisfied
But heartless wind kept blowing, blowing

I used to be my own protection (but not now)
Cause my path had lost direction (some how)
A black wind took you away (from sight)
And held the darkness overday (that night)

And the clouds above move closer
Looking so dissatisfied
And the ground below grew colder
As they put you down inside
But heartless wind kept blowing, blowing

So now you're gone
And I was wrong
I never knew what it was like
To be alone...

On the Valentine's Day
