Questions on Bharat Forecast System (BFS)

 

Q1. What is the name of India's new rain forecast system?

Ans  India's new rain forecast system is called the Bharat Forecast System (BFS).

Q2. Who developed the Bharat Forecast System (BFS)?

Ans The Bharat Forecast System (BFS) was developed by the Indian Institute of Tropical Meteorology (IITM).

Q3. What is the key improvement of the Bharat Forecast System (BFS) over the previous system?

Ans The primary improvement of the BFS is its ability to provide more fine-tuned and accurate rain forecasts down to the panchayat level. This is achieved through a significantly higher resolution in its weather forecast models.

How does the Bharat Forecast System (BFS) achieve higher resolution forecasts?

The BFS achieves higher resolution by reducing the size of the gridded squares used in its weather forecast models. The new system uses 6-km sides compared to the 12-km sides of the previous models, resulting in a four-fold improvement in resolution.

Q 4.What is the resolution of the weather forecasts provided by the Bharat Forecast System (BFS)?

Ans.The BFS provides operational weather forecasts at a 6 km by 6 km resolution.

Q What type of rain forecasts will see the most improvement with the Bharat Forecast System (BFS)?

Ans The most significant improvements with the BFS will be visible in the short- and medium-term forecasts, which have a lead time of three and seven days respectively.

Q Does the Bharat Forecast System (BFS) improve all types of weather forecasts?

Ans No, the BFS does not currently significantly improve forecasts for sudden, severe thunderstorms. Other models are used for these phenomena, and there are plans to install Doppler Weather Radars to enhance this capability.

Q What is the advantage of the new grid structure used in the Bharat Forecast System (BFS)?

Ans The new grid structure, called triangular-cubic octahedral, generates a higher density of grids and therefore higher resolution over tropical regions compared to the poles. This is beneficial because weather in tropical regions is more volatile, making higher resolution forecasts more important for forecast purposes.
