Atmospheric Optic Phenomena Matching Solution
This solution explains the physical processes behind common atmospheric optic phenomena.
Phenomenon Causation
- A. Rainbows are formed due to refraction and reflection of sunlight by water droplets in the atmosphere. Dispersion also plays a role in separating colors. The closest match is Q.
- B. Mirages are caused by the refraction of light rays as they pass through layers of air with different temperatures and densities. The correct process is P.
- C. Coronae are optical phenomena appearing as colored rings around the sun or moon, caused by the diffraction of light by small water droplets or ice crystals. The matching process is S.
- D. Halos are typically observed around the sun or moon and are formed by the refraction of sunlight through ice crystals suspended in the atmosphere. Processes involved include refraction, reflection, and dispersion. The best fit is R.
Correct Matching
Based on the analysis:
- A matches with Q (Refraction and Reflection)
- B matches with P (Refraction)
- C matches with S (Diffraction)
- D matches with R (Refraction, Reflection, Dispersion in ice crystals)
The correct combination is A : Q, B : P, C : S, D : R.
Important Questions from Physical Meteorology
- The maximum amount of water vapour which air can hold depends on
- The wavelength/colour at which solar radiation peaks is
Air rises from point A to C. At point C it reaches the dew point and begins to descend on the leeward side because it is colder than its surroundings. What will happen to the temperature of the descending air?
Read the following statements about land and sea breeze and choose the CORRECT answer.
I. The land breeze is less extensive both vertically and horizontally than the sea breeze
II. Temperature differences between land and sea are rarely as great at night as in the day time.
- Which of the following is correct?
