Onset of Monsoon Information
Monsoon season is an eagerly awaited period in India that brings relief from the scorching heat of the summer. The arrival of monsoon marks a significant change in weather patterns, and the onset of monsoon is a crucial piece of information for farmers, weather forecasters, and researchers. Here’s everything you need to know about the onset of monsoon information:
What is Monsoon?
Monsoon is a seasonal change in the direction of wind, which brings heavy rainfall in a region covering a vast area. The term ‘monsoon’ comes from the Arabic word ‘mausim,’ which means ‘season.’ The major cause of the Indian monsoon is the shift of the Intertropical Convergence Zone towards the north Indian region during summers. The monsoon season lasts from June to September, and the South-West Monsoon is the most crucial part of the Indian monsoon.
Onset of Monsoon
The onset of monsoon is considered one of the most critical weather predictions in India, primarily due to its impact on agriculture, the economy, and the lives of people. The onset of monsoon is defined as the date on which the monsoon winds hit the Kerala coast, which marks the commencement of the monsoon season. It typically begins around the first week of June and lasts until the end of September.
Factors Affecting Onset of Monsoon
The onset of monsoon relies on multiple factors, including El Nino, La Nina, and Indian Ocean Dipole. El Nino is a warm ocean current that can disrupt the typical weather pattern, resulting in a weak monsoon. On the other hand, La Nina is a cold ocean current that strengthens the monsoon. Indian Ocean Dipole is another factor that influences the onset of monsoon.
Importance of Onset of Monsoon Information
The onset of monsoon information is essential for farmers as they decide when to sow their crops based on the expected rainfall. Monsoon also plays a crucial role in hydro-electric power generation, the water level of rivers, and reservoirs. Weather forecasters use the monsoon onset information to predict the expected rainfall and issue warnings when necessary.
Conclusion
The onset of monsoon is an essential piece of information in India, and it impacts the economy, agriculture, and people’s lives. Factors such as El Nino, La Nina, and Indian Ocean Dipole can affect the onset of monsoon. The Indian Meteorological Department (IMD) issues the monsoon forecast every year, and it serves as an important source of information for decision-makers and researchers.
