Question



The law which states "In the northern hemisphere, if you stand with your back to the wind, there will be low pressure to your left and high pressure to your right," is referred to as:

A.

Kimball Law

B.

Coriolis Law

C.

Buys Ballot Law

D.

Wein Displacement Law

Correct option is C


Buys Ballot's Law describes the relationship between wind direction and pressure systems in the northern and southern hemispheres. In the northern hemisphere, if you stand with your back to the wind, the low-pressure system will be to your left, and the high-pressure system will be to your right. In the southern hemisphere, the opposite applies – low pressure will be to your right and high pressure to your left. This principle helps meteorologists and navigators determine wind and pressure patterns.
This law is fundamental in understanding atmospheric circulation and weather forecasting.
Information Booster:
1. Wind and Pressure Relationship: Wind flows from high-pressure to low-pressure areas, influenced by the Earth's rotation (Coriolis Effect).
2. Northern vs. Southern Hemisphere: Due to the Coriolis Effect, winds deflect to the right in the northern hemisphere and to the left in the southern hemisphere.
3. Practical Use: Useful for weather forecasting, especially for sailors and pilots.
4. Geostrophic Wind: Winds that result from a balance between the Coriolis force and the pressure gradient force are called geostrophic winds.
5. Named After: The law is named after Christophorus Buys Ballot, a Dutch meteorologist who formulated the principle in the 19th century.
Additional Knowledge:
· Option (a) Kimball Law: No meteorological law known by this name.
· Option (b) Coriolis Law: Describes how the Coriolis Effect causes moving objects (including air masses) to deflect to the right in the northern hemisphere and to the left in the southern hemisphere due to Earth's rotation.
· Option (d) Wein Displacement Law: In physics, this law relates to blackbody radiation and states that the wavelength at which the emission of a blackbody spectrum is maximized is inversely proportional to its temperature.
