A common feature of the weather during the pre-monsoon season, i.e., March, April and May, over the Indian region is the outburst of severe local convective storms which often turn into thunderstorm and lightning. The intense convection activity due to strong heating of land mass over Chhotanagpur plateau and movements towards southeast and mixing with warm air mass triggers the Nor Westers to develop which is locally named as Kal-Baisakhi (Bengal region) and Bardoli Cheerha (Assam). Apart from this, Mango Showers or Blossom Showers in Kerala and coastal Karnataka regions are some famous local storms of pre-monsoon season in India. Thunderstorms are characterized by towering cloud masses (mostly Cumulonimbus) with sudden electrical discharges manifested by a lightning and thunder enjoined with vigorous circulations and thus has the potential to spawn severe weather.
Formation of thunderstorms evolves in three stages
1.Cumulus Stage
2. Mature Stage
3.Dissipating Stage
Impact of pre-monsoonal rainfall
Pre-Monsoon storms mark the beginning of agricultural activities as it helps in ploughing and getting the field ready for the season. However, these storms are also associated with hailstorm and high speed winds of short duration, which are harmful for crops like mango and other standing crops.

Combating climate change effectively requires a multi-pronged approach. Transitioning to renewable energy is crucial; increasing investment in solar, wind, and other renewable sources reduces reliance on fossil fuels. Enhancing energy efficiency through stricter building standards and improved industrial practices can significantly lower emissions.
Promoting sustainable transportation is another key strategy. Accelerating the adoption of electric vehicles (EVs) through incentives and expanding charging infrastructure can reduce emissions from the transport sector. Investing in efficient public transportation and promoting walking and cycling through better infrastructure are also essential.
Implementing carbon pricing mechanisms, such as carbon taxes or cap-and-trade systems, can incentivize reductions in greenhouse gas emissions across various sectors. Protecting and restoring forests and other natural carbon sinks can help absorb CO2 from the atmosphere.
Additionally, supporting sustainable agriculture practices and reducing food waste can mitigate emissions from the food system. Public awareness and education campaigns are vital to encourage behavioral changes and support for climate policies.
International cooperation and strong political commitment are necessary to achieve these goals. By combining these strategies, we can work towards a sustainable future and effectively combat climate change.

Climate change refers to long-term shifts in temperatures and weather patterns. These changes can be natural, resulting from variations in the sun’s activity or large volcanic eruptions. However, since the 1800s, human activities—primarily the burning of fossil fuels like coal, oil, and gas—have become the main driver of climate change. The impact includes alterations in Earth’s local, regional, and global climates, affecting everything from average temperatures to extreme weather events.
The major contributors are
1.Greenhouse Gases (GHGs):
2. Industrialized Nations
Industrialized nations are defined as places where a large portion of the gross domestic product and exports comes from industrial production.
3.Land Use (deforestation, urbanization, agriculture)
All throughout human history, we have subjugated natural lands to our own purposes. Forests cover around 31% of the world and hold more than 80% of the world’s terrestrial species; however, humans are decreasing the amount of forested land and, consequently, the biodiversity housed there.
4.Waste
In a world of mass production, humans produce more waste than we know what to do with.
Around the world, about 30% of total food production is wasted either before or after it reaches its consumers. Around 2 billion tons of municipal solid waste is generated globally every year.
International Measures:
climate change results from human activities that release greenhouse gases (GHGs) into the atmosphere. Major contributors include carbon dioxide (CO₂) from fossil fuels, methane (CH₄) from livestock and landfills, and nitrous oxide (N₂O) from agriculture. International efforts, such as the Paris Agreement, aim to limit global warming, transition to renewable energy, and promote global cooperation. Let’s work together to protect our planet!
