Explanation: India's climate is influenced by its geographical location, topography, and the monsoon system. The country can be broadly divided into several climatic zones, each with distinct weather patterns and temperature ranges. The hot and humid climate is typically associated with the coastal regions of southern India, particularly Kerala and Tamil Nadu.
Kerala and Tamil Nadu are situated along the western and eastern coasts of India, respectively. These regions are heavily influenced by the southwest monsoon, which brings significant rainfall and high humidity levels. The proximity to the sea also contributes to the high humidity, as the warm ocean currents increase the moisture content in the air. The temperature in these regions remains relatively high throughout the year, with average temperatures ranging from 25°C to 35°C, making the climate hot and humid.
In contrast, other regions like Himachal Pradesh, located in the northern part of India, have a mountainous terrain and a temperate climate. The high altitude results in cooler temperatures, and the climate is not characterized by high humidity. Assam, in the northeastern part of India, does experience a humid climate due to its location in the Brahmaputra Valley and the influence of the monsoons, but it is not as consistently hot and humid as the coastal regions of Kerala and Tamil Nadu. Haryana, located in the northern part of India, has a semi-arid climate with hot summers and cool winters, but it does not have a consistently hot and humid climate.
Understanding the geographical factors that influence climate is crucial for comprehending the weather patterns in different parts of India. The hot and humid climate of Kerala and Tamil Nadu is a result of their coastal location and the influence of the monsoon system, making these regions distinct in terms of their climatic conditions.
