Explanation: In Assam, the term "Bardoli chheerha" refers to a specific windstorm known as Kalbaisakhi. This windstorm is a significant climatic phenomenon that occurs during the month of Baisakhi, which corresponds to April and May in the Gregorian calendar. The term "Kalbaisakhi" is derived from the Bengali word "Kal," meaning black or evil, and "Baisakhi," the month of April-May. This name reflects the destructive nature of the windstorm.
Kalbaisakhi is characterized by strong, dry winds that can cause significant damage to crops, particularly paddy fields, and can also affect infrastructure. The windstorm is a result of the transition period between the dry winter season and the onset of the monsoon. During this period, the region experiences a high-pressure system that leads to the formation of these strong winds.
Understanding the local terminology and the seasonal patterns of windstorms is crucial for comprehending the climatic conditions of Assam. The term "Bardoli chheerha" is a local name that reflects the impact of Kalbaisakhi on the region. It is important to note that while other regions in India may experience similar windstorms, the specific term "Bardoli chheerha" is unique to Assam and refers to Kalbaisakhi.
Students often confuse Kalbaisakhi with other seasonal winds like Loo or Mango showers. Loo refers to hot, dry winds that blow in the plains of northern India, particularly in the summer months, and are not specific to Assam. Mango showers, on the other hand, are pre-monsoon showers that occur in April and May and are beneficial for the growth of mango trees. These showers are not windstorms and do not match the description of Bardoli chheerha.
In conclusion, the correct answer is Kalbaisakhi, as it is the windstorm that is locally known as Bardoli chheerha in Assam. This windstorm is a significant climatic phenomenon that occurs during the month of Baisakhi and is characterized by strong, dry winds that can cause significant damage to crops and infrastructure. Understanding the local terminology and the seasonal patterns of windstorms is essential for comprehending the climatic conditions of Assam.
