Winds are depicted as blowing from the direction the flags are facing. Therefore, a northeast wind will be depicted with a line extending from the cloud circle to the northeast, with flags indicating wind speed on the northeast end of this line. [5] Once plotted on a map, an analysis of isotachs (lines of equal wind speeds) can be accomplished ...
The Kármán line (or von Kármán line / v ɒ n ˈ k ɑːr m ɑː n /) [2] is a conventional definition of the edge of space; it is widely but not universally accepted. The international record-keeping body FAI (Fédération aéronautique internationale) defines the Kármán line at an altitude of 100 kilometres (54 nautical miles; 62 miles ...
Line art or line drawing is any image that consists of distinct straight lines or curved lines placed against a background (usually plain). Two-dimensional or three-dimensional objects are often represented through shade (darkness) or hue . Line art can use lines of different colors, although line art is usually monochromatic.

The vortex trails produced as the wind passes over a rope produce a sound with a frequency that varies with the velocity of the wind and the thickness of the rope. [ citation needed ] Each doubling of the wind velocity results in an octave increase in the tone, allowing up to a six octave variation in a strong, gusty wind.

These high-energy stellar winds blow stellar wind bubbles. In planetary nebula NGC 6565, a cloud of gas was ejected from the star after strong stellar winds. [8] G-type stars like the Sun have a wind driven by their hot, magnetized corona. The Sun's wind is called the solar wind.
Cosmic noise, also known as galactic radio noise, is a physical phenomenon derived from outside of the Earth's atmosphere.It is not actually sound, and it can be detected through a radio receiver, which is an electronic device that receives radio waves and converts the information given by them to an audible form.
