Heatwaves in India are extreme and can have a significant impact on everyday life, affecting health, power consumption, and water supply. These conditions can be hazardous, particularly for the poor, elderly and outdoor workers.
Monsoon Season in India: June to September
Monsoon, the season of rains, is integral to life in India. It influences the country’s agriculture, economy, and culture majorly.
Overview of Indian monsoons
The Indian monsoon season usually begins in early June when moisture-laden winds from the south-west hit the Indian subcontinent.
Geographical distribution of monsoon rainfall
The Western Ghats and the north-eastern states receive the highest rainfall in the country, while the northwest region gets relatively lesser rainfall. The Thar Desert and surrounding areas are the driest, receiving very low precipitation.
Impact of monsoons on agriculture and economy
A significant portion of India’s agriculture is monsoon-dependent. It supports the sowing and growth of Kharif crops. It also replenishes reservoirs and groundwater levels, essential for irrigation and drinking purposes.
Monsoon festivals and cultural significance
Monsoons have a deep cultural significance in India. Various festivals, such as Teej and Onam, are celebrated to welcome the rains. Monsoons are also symbolic in Indian music, dance, and literature.
Post-Monsoon Season: October and November
After the monsoons recede, the post-monsoon season, also known as the retreating monsoon season, sets in.
Weather conditions during the post-monsoon season
The post-monsoon season is marked by clear skies, lower humidity and temperatures gradually becoming pleasant. Though rainfall is lower than the monsoon months, parts of South India receive significant rainfall during this period.
Regional weather variations
During post-monsoon, the north and interior regions of India start to cool down, while coastal areas maintain a slightly warmer climate.
Festivals and events during the post-monsoon season
The post-monsoon season coincides with several major Indian festivals like Navaratri, Dussehra, and Diwali. These festivals, filled with lights and fireworks, signify the triumph of good over evil.
India’s Winter Season: December to February
Winter brings respite from the intense heat in many parts of India, although the severity of winter can vary across the country.
Characteristics and variations in winter weather
Northern plains experience very chilly winters, with temperatures oftentimes dropping to near freezing levels. Fog and mist are common, reducing visibility. However, peninsular India experiences milder winters, with moderate temperatures and slight or no rainfall.
Impact of the winter season on lifestyles and festivals
During winter, people in India enjoy outdoor activities, picnics and bonfires. Important festivals like Christmas, New Year, Makar Sankranti, Pongal, and the Republic Day are celebrated with much fanfare across the country.
Regional winter weather differences
While the northern plains and hill stations experience harsh winters, coastal regions and the southern plains enjoy mild winters, with moderate day temperatures and cooler nights.
Extreme Weather Phenomena in India
India faces several extreme weather events such as cyclones, heatwaves, flash floods and droughts, each causing significant socio-economic impacts.
Cyclones and their impact
Most cyclonic activities in India occur in the post-monsoon season and affect the eastern and western coastal regions. They bring with them heavy rainfall, strong winds, and high tidal waves, causing loss of lives and extensive damage to property and crops.
Heatwaves and related health issues
During the summer, intense heatwaves can result in health issues such as dehydration, heatstroke, and even death. Heatwaves also lead to increased power consumption, pushing the power grid to its limits.
Flash floods and their causes
India experiences flash floods mostly during the monsoon season. Regions located near rivers are the most affected. Rapid urbanization, deforestation, and inadequate drainage systems add to the severity of these floods.
Drought conditions and water scarcity
Despite high rainfall during monsoons, many parts of India face water scarcity and drought conditions, especially in the summers. This notably affects the agriculture-based rural economy and leads to severe water shortages for drinking and sanitation needs.
Impact of Climate Change on India’s Weather
Climate change is affecting the world, and India isn’t untouched. It’s increasing the frequency and intensity of extreme weather events and affecting long-term weather patterns.
Increase in extreme weather events
From increasing heatwaves to more frequent and stronger cyclones, India is witnessing an uptick in weather extremes. Torrential rains causing floods in some areas contrast with severe droughts in others, affecting lives and livelihoods.
