Section E: Distinguish Between (Copyright Safe)
1. Equable Climate vs. Extreme Climate
| Equable (Maritime) Climate |
Extreme (Continental) Climate |
| Found in coastal areas (e.g., Mumbai, Chennai). |
Found in interior regions far from the sea (e.g., Delhi, Kanpur). |
| Low annual and diurnal range of temperature. Temperatures remain moderate year-round. |
High annual and diurnal range of temperature. Very hot summers and very cold winters. |
| Influenced by the moderating effect of land and sea breezes. |
Lacks the moderating influence of the sea. |
2. South-West Monsoon vs. North-East Monsoon
| South-West Monsoon |
North-East Monsoon |
| Blows from June to September (Summer). |
Blows from December to February (Winter). |
| Winds blow from sea to land (Arabian Sea & Bay of Bengal towards land). |
Winds blow from land to sea. |
| Brings heavy rainfall to almost the entire country. |
Mostly dry, but brings winter rainfall to the Coromandel Coast (Tamil Nadu). |
3. Western Disturbances vs. Tropical Cyclones
| Western Disturbances |
Tropical Cyclones |
| Originate in the Mediterranean Sea. |
Originate in the Bay of Bengal and Andaman Sea. |
| Occur during the winter season (Dec - Feb). |
Occur mainly during the retreating monsoon (Oct - Nov). |
| Bring light rain to NW India (Punjab) and snow to the Himalayas. Beneficial for Rabi crops. |
Strike the eastern coast (Odisha, Andhra) causing heavy rain, strong winds, and destruction. |
4. Arabian Sea Branch vs. Bay of Bengal Branch
| Arabian Sea Branch |
Bay of Bengal Branch |
| More powerful, strikes the Western Ghats and covers western/central India. |
Comparatively less powerful, strikes the Arakan Yoma and enters NE India and Ganga plains. |
| Provides maximum rainfall to the western coastal plains and Western Ghats. |
Provides maximum rainfall to the North-Eastern states (Meghalaya) and Northern plains. |
| Does not cause rain in Rajasthan because it blows parallel to the Aravallis. |
Moisture decreases as it moves westward up the Ganga valley. |
5. Loo vs. Kalbaisakhi
| Loo |
Kalbaisakhi |
| Hot, dry, and dusty winds. |
Violent thunderstorms with pre-monsoon showers. |
| Blows over the Northern Plains (Punjab, Haryana, UP) in May-June. |
Occurs in West Bengal and Assam in April-May. |
| Harmful, can cause heatstrokes. |
Beneficial for growing tea, jute, and rice. |
Section F: Long Answers & Give Reasons
Q1. Why does Mumbai receive more rainfall than Pune?
Reason: Relief features play a massive role in rainfall distribution (Orographic rainfall).
1. Mumbai is located on the windward side of the Western Ghats. When the moisture-laden Arabian Sea branch of the South-West Monsoon strikes the Western Ghats, the winds are forced to rise, cool, condense, and shed heavy rainfall on the coastal plains.
2. Pune, on the other hand, is located on the leeward side (rain shadow area) of the Western Ghats. By the time the winds cross the mountains and descend towards Pune, they become warm and dry, having lost most of their moisture, resulting in significantly less rainfall.
Q2. What is 'October Heat' and why is it uncomfortable?
Reason: 'October Heat' refers to the oppressive weather conditions experienced in the month of October during the period of the Retreating Monsoon.
1. As the South-West monsoon withdraws, the skies become clear, and there is a sudden increase in temperature.
2. Despite the clear skies, the ground remains waterlogged and the atmosphere holds a high amount of moisture (high humidity) from the recently concluded rainy season.
3. The combination of high temperature and high humidity creates stifling and oppressive weather, making it highly uncomfortable for people.
Q3. Give three reasons why the Indian Monsoon is considered highly unpredictable and erratic.
Reason: The Indian agriculture heavily relies on the monsoon, but its nature is highly capricious due to:
1. Uneven Spatial Distribution: Rainfall varies drastically across regions; Mawsynram receives over 1000 cm, while parts of Rajasthan receive less than 50 cm.
2. Uneven Temporal Distribution: The monsoon can arrive early or be delayed. Sometimes it rains heavily causing floods, while other times dry spells ("breaks in monsoon") cause droughts.
3. Global Weather Phenomena: External factors such as El Nino, shifting jet streams, and varying pressure differences in the Indian Ocean frequently disrupt the normal schedule and intensity of the monsoon.
Q4. Why does the Coromandel Coast remain dry in the summer but receive rainfall in the winter?
Reason:
Summer (Dry): During the South-West monsoon season, the Coromandel Coast remains dry for two reasons: First, it lies in the rain shadow area of the Arabian Sea branch. Second, it runs parallel to the Bay of Bengal branch, so the winds do not strike the coast to cause precipitation.
Winter (Wet): During October-November (Retreating Monsoon) and December-February (North-East Monsoon), winds blow from land to sea. As these winds pass over the Bay of Bengal, they pick up moisture and strike the eastern coast, bringing heavy winter rainfall to the Coromandel Coast (Tamil Nadu).
Q5. Describe the vital role played by the Himalayas in shaping the climate of India.
Reason: The Himalayas act as a massive climatic divide, providing a dual function:
1. Protection from Cold: They act as an impenetrable barrier to the freezing, dry winds blowing from Central Asia and Siberia. Without the Himalayas, northern India would be a cold desert during winter.
2. Trapping Monsoon Winds: They prevent the moisture-laden South-West monsoon winds from crossing over into Tibet. They force these winds to ascend, cool, and shed their moisture as heavy orographic rainfall within the Indian subcontinent, sustaining its river systems and agriculture.
