What are the various climatic zones of India? Briefly explain each with example.

India, owing to its vast geographical extent and diverse topography, experiences a wide range of climatic conditions. The Indian Meteorological Department (IMD) has classified the country into different climatic zones based on temperature, humidity, and precipitation. This classification is essential in building services and maintenance because the design, construction, and upkeep of buildings must align with the specific environmental conditions of each zone. Proper understanding of climatic zones ensures thermal comfort, energy efficiency, and durability of structures.

The National Building Code (NBC) of India has broadly categorized the Indian subcontinent into five major climatic zones:

1. Hot and Dry Zone

2. Warm and Humid Zone

3. Moderate Zone

4. Cold Zone

5. Composite Zone

Each of these zones has distinct climatic features that influence building design, construction materials, ventilation, heating, and cooling requirements.

1. Hot and Dry Zone
This zone is characterized by high temperatures, low humidity, and intense solar radiation. The weather remains dry for most of the year with little rainfall, and large temperature fluctuations are common between day and ___ _______ ______ ______ _______ ________ ____ _______ ____ _________ __________.
