First there is a traveling tropical disturbance, which can cause air in the developing cyclone to rise.
Then it acquires cyclonic circulation around a center of low pressure, called a tropical depression.
If winds then exceed 65 km/hr it is called a tropical storm.
Largest number of stars in our galaxy is located in a disk. They have nearly circular orbits around black hole which is located in a center of galaxy. Orbits of all these stars have same orientation. Some of orbits have small inclination which causes for stars to move little up and down.
Halo stars are located in a "bubble" around our galaxy. These stars travel high above and far below the disk on orbits with random orientations. These are stars that once were located in a disk but they went outside of it.
Bulge stars are located in a center of our galaxy. They also orbit black hole and they have much shorter period of orbit than all other stars in a galaxy. Their orbits have random orientations.
They have a Dictatorship, because their Government controls all factories, businesses, what you do, and where you go.
