Identifying National Parks with Diverse Climate Zones

The question asks us to identify a National Park in India that experiences a wide range of climate zones, specifically from tropical to subtropical, temperate, and even arctic-like conditions. This kind of climatic diversity is usually linked to a significant variation in altitude within the park.

Analyzing the Options

Let's look at the given options and consider their geographical locations and typical climates:

• Khangchendzonga National Park: Located in Sikkim, this park is in the high Himalayas. Its climate ranges from subtropical to alpine and tundra, reaching very high altitudes near Mount Kangchenjunga.
• Nanda Devi National Park: Situated in Uttarakhand, this park is also in the high altitudes of the Western Himalayas. It primarily experiences an alpine climate.
• Neora Valley National Park: Located in West Bengal, this park is in the Eastern Himalayas but at comparatively lower to moderate altitudes. Its climate is generally subtropical to temperate.
• Namdapha National Park: Located in Arunachal Pradesh in the Eastern Himalayas, this park is known for its significant altitudinal variation, ranging from about 200 meters to over 4,500 meters above sea level.

Why Namdapha National Park Fits the Description

Due to its vast altitudinal range, Namdapha National Park encompasses several distinct climatic zones:

• Tropical and Subtropical: Found in the lower valleys and areas (around 200-800 meters).
• Temperate: Experienced at mid-altitudes (around 800-3500 meters).
• Alpine and near-Arctic: Found at the highest reaches of the park (above 3500-4500 meters and beyond), where temperatures are very low, and conditions can be harsh, similar to arctic environments.

This unique altitudinal spread allows Namdapha National Park to harbour incredible biodiversity across these varied climates.

Comparison of National Parks and Climate Zones

Based on this comparison and the information about the altitudinal range, Namdapha National Park is the park among the options that most accurately fits the description of having a climate that varies from tropical to subtropical, temperate, and arctic.

Additional Information: Altitude and Climate Diversity in National Parks

The primary reason a national park can have a climate ranging from tropical to arctic is a significant difference in elevation from its lowest points to its highest peaks. This phenomenon is known as altitudinal zonation.

• As altitude increases, temperature generally decreases. This is why low-lying areas can be tropical or subtropical, while high mountain areas can be alpine or even have conditions similar to arctic regions.
• Factors like latitude, proximity to water bodies, and prevailing winds also influence the specific climate zones present within a park.
• National Parks with large altitudinal variations, like Namdapha, serve as crucial refuges for species adapted to different climates and play a vital role in conservation across multiple ecosystems.
• These diverse climate zones support a wide variety of flora and fauna, making such parks biodiversity hotspots.
