Question

8. About the measurements of atmospheric winds on Jupiter, which one is NOT correct?

(A) The current wind measurements on Jupiter are generally referred to its solid surface.

(B) We can estimate the wind speeds by tracking the clouds on a series of images of Jupiter.

(C) Thermal wind equation can be used to calculate wind field from observed temperature on Jupiter.

(D) The rotation period of Jupiter’s magnetic field is basically constant with time, so it can be used as a reference for the wind measurements on Jupiter.

Answer 1

Let us begin this question by understanding about the Atmospheric winds on Jupiter ,

Then , we will reject the options according to our requirements to achieve the final answer .

The atmosphere of jupiter is largest among all planets in the Solar system . So when it comes to the measurements of the atmospheric winds on Jupiter

Jupiter has most powerful storms and followed by lightning strikes. There are sites of strong upward motion of air which results in the formation of bright and dense clouds.

The storms are a result of moist convection in the atmosphere connected to the evaporation and condensation of water.

The storms form mainly in belt regions. The lightning strikes on Jupiter are many times more stronger than those seen on Earth, and are assumed to be associated with the water clouds .

The atmospheric analysis is made using the changes observed in the images of atmosphere of Jupiter .

So , the We can estimate the wind speeds by tracking the clouds on a series of images of Jupiter

Now , Also the Thermal Wind Equation is used to calculate the wind speed .

Also Jupiter's magnetic field rotates at the same speed as the region below its atmosphere

Hence , option A is not correct .
