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.
What is a trough aloft generally associated with?
A trough aloft is generally associated with unstable weather conditions, such as the potential for thunderstorms, heavy rain, and strong winds. This is because a trough aloft represents a region of lower pressure in the upper atmosphere, which can lead to the development of unsettled weather patterns.
What is inversion aloft?
Inversion aloft refers to a situation where the temperature in the atmosphere increases with height instead of decreasing, as is typically the case. This can lead to stable atmospheric conditions that inhibit vertical mixing of air and can result in trapped pollutants or fog at the surface. Inversions aloft are common in certain weather patterns, such as high pressure systems.
Is cold air aloft associated with low or high pressure?
Cold air aloft is associated with a surface low pressure system. The reverse is true for warm air aloft. In a baroclinic low pressure system, the upper-level low/trough is usually situated over the cold air, while upper level highs/ridges are around warm air aloft.
What is carried aloft by a weather balloon to measure upper level pressure?
A+ Radiosonde

What element is used in balloons to keep them in the air?
Helium (Hydrogen could also be used but this is flamable). Not some balloons are also kept aloft using hot air.

What weather instrument Carries weather instruments aloft to about 30000's meters?
A weather balloon carries weather instruments, such as a radiosonde, aloft to about 30,000 meters. As the balloon ascends, the instruments collect data on temperature, humidity, and pressure, transmitting the information back to the ground for weather forecasting and research.
What is convergence aloft and divergence?
Convergence aloft refers to the process where air masses come together at higher altitudes, leading to a decrease in air pressure and often resulting in rising air and cloud formation. This phenomenon typically occurs in the upper levels of the atmosphere and is associated with storm development. Conversely, divergence occurs when air masses spread apart at high altitudes, causing air to sink and often leading to clearer skies and stable weather conditions. Both processes are critical in understanding weather patterns and atmospheric dynamics.
What causes an inversion in the atmosphere?
An inversion in the atmosphere is caused by a layer of warm air trapping cooler air near the surface, preventing it from rising. This can happen due to factors like calm weather conditions, radiation cooling at night, or the presence of a temperature inversion aloft.
What causes instability in the atmosphere?
Instability in the atmosphere can be caused by factors such as warm air at the surface rising rapidly, presence of cool air aloft, or the release of latent heat during processes like condensation and freezing. These conditions can lead to the formation of thunderstorms, severe weather, or rapid changes in weather patterns.
Is a engine essential to keeping a blimp in the air?
No. helium gas inside the blimp keeps it aloft. Just like a helium makes balloons fly!!
Are Surface cyclones accompanied by divergence aloft?
Yes, surface cyclones are typically accompanied by divergence aloft in the upper levels of the atmosphere. This divergence allows for rising air and helps to enhance the development and intensification of the surface cyclone.
