Introduction Summary of types of fixed balloons tethered balloons high profile balloon stratospheric balloon materials such as rubber or plastic ball made of leather, filled with hydrogen, helium, air-light gas geometric , carry the equipment off, the high-altitude meteorological observations observation platform. It has the characteristics of low-cost increase without power. And the ground is not connected to a weather balloon is called the free balloons, and ground connections with a cable called a tethered balloon balloons. Production of materials and size of the balloon by their use to determine. Review type of weather balloons in the early stage of development, has applied to hot air or hydrogen filling the paper or textile leather ball. The 19th century, has done a good rate of expansion of the balloon is made of rubber, which increases the height of the balloon can reach up to expand the scope of the upper air sounding. 60 years of the 20th century large-scale non-expansive balloons in the boundary layer of plastic film detection, high levels of global exploration and the default stratosphere (see atmosphere) detection tests for a wide range of applications has been increasing. ,cheap tiffany jewelry, Balloons to carry the equipment up to high-altitude measurements of meteorological elements, or high-altitude wind measurement equipment for the electronic equipment, or both of the free balloon (see color). For in the air, especially in higher level in the atmosphere, the ,Tiffany Jewellery Outlet, temperature sensor from solar radiation, in addition to application of radiation thermometer covers, we must also make sufficient ventilation, for balloons to be up to the start up speed 5 ~ 6 m / sec. Balloons can reach the maximum height that the ball when the critical height of rupture of the skin, basically depends on the quality of rubber ball skin. Rise in other conditions and circumstances are the same speed, the ball thicker skin, you can reach the height of the balloon higher. The weight of daily use balloons of about 1 kg, 85?? up to 30 km height. Tethered balloon winch with a cable tethered to the ground on the weather balloon. With the increasing level of wind speed, tethered balloon to increase ,Tiffany Jewelry On Sale, the tilt increases, therefore, difficult windy days were observed. Tethered balloon in order to have good stability in air, sometimes made into sleek shape of the balloon (see color). Equipment or directly carried by the balloon in the sky to observe the process, or hanging in the cables of different heights were observed. It can be a longer period of time (a few hours to a few hours) and continuous measurement of the selected meteorological factors on changes in height, rather than sounding balloons can only be a one-time measurement, and the measured values within the atmosphere represent a average. Tethered balloon soundings especially for air pollution monitoring and research of atmospheric boundary layer. Set high in the atmosphere to keep the balloon in such a smooth surface density of free balloons drift with the flow. Life depends on the setting of high balloon balloon balloon material and the height of the work. For the balls and keeping the skin strong air pressure is good, common polyethylene film and polyester film, or pressed by the multi-layer plastic film composite membrane. Membrane skin can reduce the ball the ball out of gas emission rate, experienced a small amount of excess pressure (the pressure more than atmospheric pressure inside the ball), to extend ,Tiffany Rings, the life of the balloon. Also can be used to open the bottom vents in the balloon method, the skin to maintain zero pressure the ball state (air pressure equal to the ball inside and outside) to prevent balloon rupture. Drift set in a few km altitude balloons vulnerable to ice and high mountains of the broken sink, and 10 to 20 km altitude above the fixed high-altitude balloons, may work a few months to 2 years. The inflated balloon the balance to be met by the height and the total ,Tiffany Accessories, weight of the balloon and equipment to determine. At present a large set of high balloon can carry 300 to vote under the radiosonde, according to the instructions from the weather satellites in designated areas under the cast, the measurement data collected by a set of high balloon to the ground station and then transmitted via satellite. This combination of fixed and satellite high-called mother set high balloon balloon system. Given air mass properties in the measurement of high balloon change and atmospheric electrical characteristics has been widely used. Global Atmospheric Research Program 70 the first global study, a large number of applications has been set high at the equator of the balloon and the lower latitudes and the global level over the southern hemisphere atmospheric ,Tiffany Bracelet, detection, using a named Ghost (GHOST) balloon. Stratospheric balloon rose to stratospheric height detection of large weather balloon (see color). It uses ? technologies such as locating and tracking remote telemetry, unlike conventional radio sounding balloons and set high balloon. Instruments it carries can be recycled in the designated areas under the cast. Stratospheric balloons can be observed meteorological elements, atmospheric composition, atmospheric electricity, atmospheric ozone, solar ,Tiffany Charms, radiation, verify pressure - high formula (see balance of atmospheric motion) and so on. Stratospheric balloon with 10 to 30 million cubic meters or greater volume, after hydrogen charging 100 to 150 kg load equipment. Has a load of 1,000 kilograms or more of the large balloon. Stratospheric balloon is able to complete 20 to 40 km or more observations of upper air sounding platform. Shifangqiqiu generally select the appropriate season and weather conditions, combined with the height of the wind direction, wind speed to control the situation, for example, the horizontal position of the balloon using high, low wind orientation: the lower the eastward shift of the westerly winds make the balloon until the rise to the stratosphere Shiyou use of high-level easterly winds move westward in order to complete the ,Tiffany Cufflinks, whole process of exploration as close as possible after the release site and recycled; balloon's lift from the ground remote control of the exhaust valves and balancer to control the property or sell-off compartment . Now mainly used for detection of stratospheric balloon of scientific experiments, not only for atmospheric composition, ozone, solar constant, radiation detection, etc., but also for high-energy physics, astronomy, space physics and other subjects of the probe.
