Cloudbursts are intense, sudden rainfall events that can release extraordinary amounts of water over a small geographical area within a very short time, often leading to flash floods and severe damage. Understanding the reasons behind cloudbursts involves exploring meteorological, geographical, and climatic factors that collectively contribute to their formation. Below is an extensive explanation of the reasons behind cloudbursts, drawing on scientific information and examples primarily from mountainous regions such as the Himalayas, where the phenomenon is most common. Definition and Nature of Cloudbursts A cloudburst is officially defined by meteorological agencies like the India Meteorological Department (IMD) as rainfall exceeding 100 millimeters (10 cm) within an hour over a localized area typically less than 20-30 square kilometers. Unlike regular rainfall spread over hours or days, cloudbursts produce intense precipitation in a very short span, resulting in flood-like...
Nuclear energy has been harnessed in many positive ways since its discovery, contributing significantly to electricity generation, environmental protection, medical advancements, scientific research, and national security. Below is a detailed discussion explaining how nuclear energy has been used positively across various sectors. 1. Clean and Reliable Electricity Generation One of the primary positive uses of nuclear energy is its role in producing large amounts of low-carbon electricity. Nuclear power plants generate about 10% of the world's electricity and are responsible for nearly 20% of electricity in some countries like the United States. Unlike fossil fuels such as coal, oil, and natural gas, nuclear energy produces virtually no carbon dioxide or greenhouse gas emissions during operation, which helps reduce air pollution and combat climate change. For instance, in the U.S., nuclear energy avoids over 471 million metric tons of carbon emissions each year, equivalent to r...
