Dry air is caused by low humidity. When relative humidity drops to 40% the air will feel dry to the skin. Water vapor in the air also depends on the dewpoint of the air. When there is low vapor there is a fixed percentage by volume or mass of oxygen, nitrogen, and argon.
Nothing in particular "attracts" tornadoes in a literal sense. However, they are most likely to form under a certain set of weather conditions. In most basic terms, when thunderstorms encounter wind shear, or differences in speed and direction with altitude, they can start rotating and, in turn, produce tornadoes. Thunderstorms normally develop when warm, moist air exists beneath layer of cold air. The strongest storms, those most likely to produce tornadoes, most often form along fronts, when air masses with different properties collide.
The 2013 Moore tornado happened in much the same way that other violent tornadoes happen. A slow-moving low-pressure system moved out over the Great Plains. The collision of warm, moist air from the Gulf of Mexico, cool air from Canada, and dry air from the Rockies associated with this system caused severe thunderstorms to develop across the Great Plains. Strong wind shear set some of these storms rotating, turning them into supercells, the kind of thunderstorm most likely to produce a tornado. Some of these did go on to produce tornadoes. On May 20, a particularly intense supercell spawned a tornado near Newcastle, Oklahoma. The west-northwest track of this tornado, a common direction to take, sent this tornado straight through Moore.
Tornado Alley is an area in the central U.S. with ideal conditions for tornado formation due to a combination of warm, moist air from the Gulf of Mexico colliding with cool, dry air from the Rocky Mountains. This clash of air masses creates rotating updrafts that can lead to the development of tornadoes.
The United States has the most most prolific tornado-producing area in the world: Tornado Alley. This regions stretches across the plains in the middle part of the country. Here, warm moist air from the Gulf of Mexico meets cool air from Canada and sometimes warm air from the Rockies. This can produce very powerfult thunderstorms. Shifts in wind speed and direction with altitude, called wind shear, set these storms rotating, turing them into supercells, the primary producers of tornadoes, especially strong tornadoes. Related effects in adjacent regions lead to a high rate of tornado occurence in most of the region between the Appalachians and the Rockies. Such a large region that is prone to tornadoes brings the average number of tornadoes in the U.S. to more than 1,200 per year. In addition to being more frequent, American tornadoes also tend to be the most violent, making them more likely to become major news items.
If you are referring to the tornadoes that struck Alabama early on January 23, 2012, a low pressure system centered to the north produced a cold front. As this front moved through Alabama it lifted the warmer, moister air ahead of it. The moisture in this air condensed as a result, forming thunderstorm. Wind shear (a condition in which the speed and direction of wind changes with altitude) then set these storms rotating. The rotation in some of these storms produced tornadoes.
An air conditioner does not have a specific temperature setting; rather, it cools the air to a desired temperature set by the user. Therefore, an air conditioner set to 60 degrees will produce colder air than one set to 70 degrees because it will cool the air to a lower temperature.
Is the theremostat set to Fan On? If not, is your house getting to the set temperature? If it is there could be a problem with the thermostat or it is wired incorrectly.
The player makes the strings vibrate, which makes the body of the guitar vibrate, which makes the air vibrate. And vibrations in the air, at a certain set of frequencies, is what sound is.

so that they can actually know how much they're making or losing. As opposed to blindly wandering about with their fingers in the air.

Yes, a drum set radiates sound energy when it is played. This sound energy is generated through the vibrations of the drum heads and cymbals, which produce the audible sound waves that propagate through the air.

The set of conditions specified for the behavior of the solution to a set of differential equations at the boundary of its domain. Boundary conditions are important in determining the mathematical solutions to many physical problems.
It sets up two circulation cells where warm air aloft moves toward the poles and cool surface air moves toward the equator.
There is no set temperature that the central air should be set to. Most people choose to set this temperature to about 70 degrees Fahrenheit.
