Advanced Dvorak Technique (ADT)

Why in news?

• American meteorologist Vernon Dvorak, credited for developing the Advanced Dvorak Technique (ADT) in the 1970s, has passed away.

About Advanced Dvorak Technique (ADT):

• Advanced Dvorak Technique (ADT) is a widely used system to estimate tropical cyclone intensity.
• This technique utilizes the available satellite images obtained from polar-orbiting satellites to examine the features of the developing tropical storms (hurricanes, cyclones and typhoons).
• During the daytime, images in the visible spectrum were used while at night, the ocean would be observed using infrared images.
• This technique cannot help make any predictions, or measure wind or pressure or any other meteorological parameters associated with the cyclone. But it is a guide to estimate the storm’s intensity and possible intensification.

Significance:

• This technique is said to be one of the greatest meteorological innovations.
• Even in the present day, when forecasters have access to several state-of-the-art tools like model guidance, animations, artificial intelligence, machine learning and satellite technology, this technique continues to be widely used.
