The seasonal reversal of winds is the typical characteristic of

Result
Your answer:  ·  Correct: C
Explanation

The seasonal reversal of winds is the typical characteristic of Monsoon climate.[2] Monsoon connotes the climate associated with seasonal reversal in the direction of winds.[3] Unlike the equatorial wet climate, the monsoon climate is characterised by distinct wet and dry seasons associated with seasonal reversal of winds.[4] The monsoons are characterized by seasonal reversal of wind direction.[5]

In contrast, Mediterranean climates experience wet, mild winters and hot, dry summers, but the wind patterns do not undergo a significant seasonal reversal.[6] The equatorial climate is characterized by uniformly high temperatures and rainfall throughout the year without marked seasonal wind reversals. Therefore, only the monsoon climate exhibits this distinctive feature of seasonal wind reversal, making option C the correct answer.

This is a 'Definition-Check' question. The term 'Monsoon' itself is derived from the Arabic 'Mausim', literally meaning seasonal reversal of winds. If you read the first paragraph of the NCERT chapter on Climate, you answer this in 5 seconds. Do not over-analyze wind shifts in other climates; look for the *defining* characteristic.

How this question is built

This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.

Statement 1
Is seasonal reversal of winds a typical characteristic of the equatorial climate?
Origin: Web / Current Affairs Fairness: CA heavy Web-answerable

Web source
Presence: 5/5
"**Answer: (c)** **Option (c) is correct:**The seasonal reversal of winds is the typical characteristic of Monsoon climate."
Why this source?
  • Directly answers the question in a multiple-choice format: identifies which climate has seasonal reversal of winds.
  • Explicitly states that seasonal reversal of winds is a typical characteristic of the Monsoon climate (not the equatorial climate).

Presence: 4/5
"The monsoon is nowadays recognized as a global-scale, three-dimensional atmospheric circulation characterized by seasonal reversal in surface ..."
Why this source?
  • Defines the monsoon as an atmospheric circulation characterized by seasonal reversal in surface winds.
  • Supports that seasonal wind reversal is a defining feature of monsoon systems, reinforcing that this trait is monsoon-specific.

Strength: 5/5
“• Unlike the equatorial wet climate, the monsoon climate is characterised by distinct wet and dry seasons associated with seasonal reversal of winds. Usually, there are three seasons namely summer, winter and the rainy season (seasons are the chief characteristic of monsoon climate). Floods in the wet season and droughts in the dry season are common.”
Why relevant

Explicitly contrasts equatorial wet climate with monsoon climate, stating monsoon climate is characterised by distinct wet/dry seasons associated with seasonal reversal of winds (implying the equatorial wet climate lacks this).

How to extend

A student could combine this with a map of equatorial regions to check whether areas at the equator generally show monsoon-type seasonal wind reversals or steady conditions.

“• 1. The most distinctive feature of the hot, wet equatorial climate is its A large annual range of temperature B double maxima of rainfall coinciding with the equinoxes C distinct dry and wet seasons D heavy summer rain 2. The sketch on Fig. 15.3 on page 152 shows the characteristic features of an equatorial rain forest. It attempts to illustrate the A compactness of the forest B presence of undergrowth C absence of climbers D distinct three-layer arrangement of the trees rhythm of temperature and rainfall, what evidence suggests that the station is located on a highland? • A It has an irregular pattern of rainfall • B Its total annual precipitation is heavy • C It has a uniformly low temperarure • D It has no distinct seasons • 5.”
Why relevant

States a key feature of the hot, wet equatorial climate is 'no distinct seasons', which suggests absence of the seasonal wind-reversal pattern that defines monsoons.

How to extend

Extend by comparing monthly wind/seasonality charts for equatorial stations vs known monsoon regions to see if reversal occurs.

Strength: 4/5
“The equatorial, hot, wet climate is found between 5" and 10' north and south of the equator. Its greatest extent is found in the lowlands of the Amazon, Malaysia, and the East Indies. Further away from the equator, the influence of the on-shore Trade Winds gives rise to a modified type of equatorial climate with monsoonal influences.”
Why relevant

Notes equatorial hot, wet climate occurs within about 5–10° of the equator and that farther from the equator 'the influence of the on-shore Trade Winds gives rise to a modified type of equatorial climate with monsoonal influences' (implying monsoonal reversal is more peripheral).

How to extend

Use latitude information on a world map to test whether seasonal wind reversals are more common away from the immediate equatorial belt.

Physical Geography by PMF IAS, Manjunath Thamminidi, PMF IAS (1st ed.) > Chapter 23: Pressure Systems and Wind System > Equatorial Low-Pressure Belt or 'Doldrums' > p. 311
Strength: 4/5
“• The equatorial low-pressure belt lies between 10° N and 10° S latitudes. Its position varies with the apparent movement of the sun seasonally between 5° N and 5° S and 20° N and 20° S.• This belt happens to be the zone of convergence of trade winds (Intertropical Convergence Zone or ITCZ) from two hemispheres from sub-tropical high-pressure belts.• This belt is also called the doldrums, because of the extremely calm air movements.”
Why relevant

Describes the equatorial low-pressure belt/ITCZ as a zone of convergence/doldrums with extremely calm air movements, which is inconsistent with a regular, large-scale seasonal wind reversal at the equator itself.

How to extend

Compare the seasonal migration of the ITCZ (given here as varying seasonally) with expected wind-reversal patterns to infer if equatorial zones experience systematic reversals.

“Thus, equatorial westerlies are established over these areas. The equatorial westerlies become south-west or summer monsoons. On a rotating earth, the trade winds of the Southern Hemisphere after crossing the equator turn towards their right (Coriolis effect) (Fig. 4.5). The NITC is associated with numerous atmospheric storms (cyclones) which yield heavy rainfall during wet monsoon months (July to September). Similarly, the north-east or winter monsoon does not originate only due to low pressure in the Southern Hemisphere during winter solstice (when the Sun's rays are vertical over the Tropic of Capricorn). In fact, the north-east monsoons are north-east trade winds which are re-established over south-east Asia due to southward shifting of pressure and wind belts.”
Why relevant

Explains how equatorial westerlies can become monsoon winds after crossing the equator and being deflected (Coriolis), showing monsoon reversal involves cross-equatorial dynamics rather than being intrinsic to the equatorial belt.

How to extend

A student could check which regions experience these cross-equatorial wind shifts (e.g., using hemisphere positions and seasonal sun migration) to see if they coincide with equatorial climates or lie adjacent to them.
