**Temperate Cyclones:**
– **Formation:** Occur in mid-latitudes (30°-60°) due to the interaction of different air masses, often involving cold and warm fronts.
– **Structure:** Have a complex structure with multiple fronts and more asymmetric wind circulation.
– **Size:** Generally larger, spanning hundreds to over a thousand kilometers.
– **Energy Source:** Derive energy from temperature contrasts between air masses.
– **Weather:** Associated with diverse weather conditions (rain, snow, sleet, strong winds) and prolonged precipitation.
– **Seasonality:** Can occur year-round but are more common in fall, winter, and spring.
– **Impact Areas:** Affect mid-latitude regions like North America, Europe, and Asia.
**Tropical Cyclones:**
– **Formation:** Occur in tropical/subtropical regions (5°-30°) over warm ocean waters, gaining strength from heat and moisture.
– **Structure:** Have a symmetric structure with a well-defined eye, eyewall, and spiral rainbands.
– **Size:** Smaller, typically 100-500 kilometers in diameter.
– **Energy Source:** Derive energy from latent heat released during moist air condensation.
– **Weather:** Associated with heavy rainfall, strong winds, thunderstorms, and storm surges, leading to severe flooding and damage.
– **Seasonality:** Form during late summer and early fall when ocean temperatures are warmest (e.g., Atlantic hurricane season from June 1 to November 30).
– **Impact Areas:** Affect tropical and subtropical regions, including the Americas, Southeast Asia, Indian subcontinent, and Pacific Islands.
These cyclones differ in formation, structure, size, energy source, weather impacts, seasonality, and regions affected.

Agriculture has been the backbone of India’s economy for centuries, and it continues to play a vital role in the country’s economic development. The sector’s significance and contribution to the GDP have evolved over the decades, influenced by various factors such as technological advancements, government policies, and changing consumer preferences.
Significance of Agriculture in India’s Economy:
Contribution to GDP:
- Historical Context: In the 1950s and 1960s, agriculture contributed around 50% to India’s GDP.
- Post-Green Revolution (1970s-1980s): With the introduction of high-yielding varieties of crops and irrigation facilities, agricultural productivity increased, and its contribution to GDP rose to around 35%.
- 1990s-2000s: The liberalization of the economy led to increased competition and specialization, causing agricultural growth rates to slow down. Its contribution to GDP dropped to around 20%.
- 2010s-present: The agricultural sector has experienced a moderate growth rate, with its contribution to GDP stabilizing around 18%.
