Answer
A radiosonde flight is called a "sounding" and can done at other times as suggested above, if not one-off soundings for severe weather events, usually 06 and 18z. Most radiosondes give temperature, humidity and pressure data, other specialised high altitude sondes measure ozone (and since the sondes are so large, often have a smaller temperature sonde attached so the balloon flight is more useful). Some sondes also measure wind speed and direction via GPS (which doubles the cost of the sonde). Stations which have a windfinding radar use the simpler sondes with a radar target suspended under the balloon for wind data.
Finnish Vaisala sondes have 60 metres of string on an unwinder attached to the sonde. This acts like a "sea anchor" while aloft, stabilising the balloon train in turbulent air, and which keeps the sonde away from the balloon after release both to protect the balloon from the sonde aerial and sensor array, and to ensure that the sonde is passing through air undisturbed by what can be a large spherical object- the balloon.

What is carried aloft by a weather balloon to measure upper level pressure?
A+ Radiosonde
What can a meteorologist find from a weather balloons?
It's meteorologist, and balloons are generally sent aloft by technicians or observers, not meteorologists, who analyse the data found. Data obtainable from balloons includes wind speed and direction, as well as pressure, temperature and humidity. The balloon merely carries equipment aloft, they provide no data directly, except where balloons are tracked optically by theodolite, a rarely used technique these days.
When winds blow parallel to the isobars which is usually the case for winds aloft they are called?
geostrophic
Warm air aloft is usually associatd with?
Its usually associated with some type of frontal uplift. Hope this helped!
Which measures upper atmospheric weather conditions?
I believe the answer you seek is the radiosonde, which is attached to a weather balloon.A. Pilot Balloon/TheodoliteA Pilot Balloon is a meteorological balloon that is filled with gas lighter than air. When the pilot balloon is used in conjunction with a theodolite it is used to determine the speed and direction of winds at different levels of the atmosphere.The theodolite is similar to an engineer's transit. It consists of a sighting telescope mounted so that it is free to rotate around a horizontal and a vertical axis and has graduated scales so that the angles of rotation maybe measured while tracking the pilot balloon.The elevation angles and azimuths of the balloon are recorded from the theodolite and these data at the end of the flight which may last for more than an hour are plotted to a plotting board. The wind speed and direction at selected levels are calculated either by trigonometric methods or graphical methods.Night observation is accomplished by attaching a lit paper lantern to the balloon.B. RadiosondeRadiosonde, an airborne instrument used for measuring pressure, temperature and relative humidity in the upper air is the radiosonde. he instrument is carried aloft by a meteorological balloon inflated with hydrogen. The radiosonde has a built-in high frequency transmitter that transmits data from the radiosonde meter and recorded on the ground by a specially designed radiosonde receiver.C. RawinsondeA more sophisticated version of this instrument is the rawindsonde. The rawindsonde is an electronic device used for measuring wind velocity, pressure, temperature and humidity aloft. It is also attached to a balloon and as it rises through the atmosphere, it makes the required measurements.D. RawinAnother special instrument is the Rawin which is short for Radar and Wind. It is an electronic device that measures pressure, temperature and humidity.E. Wind Finding RadarAnother instrument is the Wind Finding Radar. It determines the speed and direction of winds aloft by means of radar echoes. A radar target is attached to a balloon and it is this target that is tracked by ground radar. The bearing and time of interval of the echoes is evaluated by a receiver.F. Weather Surveillance RadarA Weather Surveillance Radar is of the long range type which detects and tracks typhoons and cloud masses at distance of 400 kilometers or less. This radar has a rotating antenna disk preferably mounted on top of a building free from any physical obstruction. Radio energy emitted by the transmitter and focused by the antenna shoots outward through the atmosphere in a narrow beam. The cloud mass, whether it is part of a typhoon or not, reflects a small fraction of the energy back to the antenna. This reflected energy is amplified and displayed visually on a radar scope. The distance or slant range of the target from the radar is determined through the elapsed time the signal is transmitted and then received as an echo. Its direction is determined by the direction at which the focused beam is pointing at the instant the echo is received. The radar is a useful tool in tracking and monitoring tropical cyclones.
What weather instrument Carries weather instruments aloft to about 30000's meters?
weather balloon
What is carried aloft by a weather balloon to measure upper level pressure?
A+ Radiosonde
What is the device that is sent up into the air to measure the weather?
A radiosonde (RAY dee oh sawned) is a device that is sent up on a weather balloon to study weather conditions aloft.
What is an instrument carried aloft by a weather balloon to measure upper level pressure temperature humidity and winds?
Radiosonde is the general term.
How many minute does a balloon rocket goes?
The question is not well-formed. Similar questions may include: How many minutes does a helium balloon stay aloft? How long does a hot air balloon stay aloft? How long does a particular rocket motor burn?
What keeps a hot air balloon aloft?
Hot air is lighter. See the related link.
What keeps hot air balloons aloft?
the hot air inside the balloon is what's keeping the balloon aloft. the explanation is hot gases or air is lighter than cold air so hot air will rise since it is lighter than the cold air.
Who kept a balloon in the air for the longest time?
Bertrand Piccard and Brian Jones when they flew around the world in 1999. They were flying a very special balloon, a combination of a helium and a hot air balloon and were aloft for 477h 47m.
What makes hot-air balloon drift downwards?
Balloons start to lose altitude when the air inside the envelope cools off. In order to keep the balloon aloft the balloon pilot uses a burner to heat up the gases inside.
What can a meteorologist find from a weather balloons?
It's meteorologist, and balloons are generally sent aloft by technicians or observers, not meteorologists, who analyse the data found. Data obtainable from balloons includes wind speed and direction, as well as pressure, temperature and humidity.

What are pellets of ice called?
In the US, cold weather ice pellets are called sleet(frozen rain), or more rarely graupel, which consists of ice crystals that collect on snowflakes.Warm weather ice is hail, in which layers of ice build up on a nucleus as the ice is lifted aloft in thunderstorms.
How does a burner flame cause a balloon to rise and stay aloft?
As the flame burns it heats the air around it making the air less dense than the cooler air above, the warm air particles rise to the top of the balloon and the balloon rises with the air. Essentially a hot air balloon uses a convection current to stay in the air.
