Aspi Day 2019

On Friday, 29th of April 2019, SMAN 3 Bandung held an event called "Aspiration Day." It's an event where we students can speak up our aspiration to make our school be better in every aspect, like giving some advices.

This event started from 1 p.m. The topic is "How to Deliver Your Aspiration". Actually our governor, Mr. Ridwan Kamil was supposedly come to give a talkshow, but unfortunately he can't due to some other business. So in return a guest speaker, Mrs. Diah, came as Mr. Ridwan Kamil's substitute. She told us that if we are a leader of a community, we must have good communication skills, be a caring person, able to manage all problem, be trusted by our follower, can make the right decisions in hard times, and be an open-minded person. That way we can become a great leader for our follower and ourselves.

Beside Mrs. Diah, Mrs. Keri as the Vice Rector of Padjajaran University also came. She told us about how to make your aspiration noticed. Here are what she said:
1. We must be sure that our aspiration is worth delivered.
2. It has to be logic and supported with factual datas to strengthen our aspiration.
3. Find the "right person" to tell about our aspiration.
4. Always being polite when delivering our aspiration.
5. If we deliver it together with our community, the aspiration will have a higher chance to be noticed.

After all of the program finished, "Aspiration Day 2019" was closed nicely with the performance of Musik Klasik 3 and Amygdala.

Natural Phenomenon

What is a fire tornado?
A fire tornado is a combination of heat, ash, and fire into a spinning mass of air.
Actually, fire tornado are more closely related to whirlwind than they are to full-fledged tornado because the vortex in most cases does not extend from the surface to the cloud base. But because they also involve a mass of rotating air rapidly around a central axis, similar to tornado, we can still call it fire tornado although the most exact name should be fire whirl. They form in certain situations, such as wildfires, large fires spawned by natural disasters, and, in some cases, house fires.

There are 3 types of tornado, that is supercell (can cause significant damage), non-supercell (any other tornadoes beside supercell), and whirlwind (tornado-like storms). Fire tornadoes are in the last cathegory. 

How did a fire tornado form? First a very big heat source near the ground existed, and causing a column of superheated air. When the fast wind high above the ground met the slower one near the ground, it will create a mass of spinning air alongside with the column of superheated air. When it met an updraft and the updraft is strong enough, it will raise the spinning air from horizontal to vertical.

Fire tornadoes are dangerous. That's why we should maximize our effort to prevent it, such as not making a wildfire in the forest, and not letting a very big heat source exist uncontrollably in the open air.
