WHAT SCALE IS USED TO RANK THE INTENSITY OF TORNADOES? BRIEFLY EXPLAIN HOW THIS SCALE WORKS

|
|
|
WHAT TORNADO RANKING SCALE WAS RECENTLY UPDATED? WHY? WHAT IS THE PRIMARY DIFFERENCE BETWEEN THE OLD AND NEW SCALES?
|
The fujita scale was updated and is now called the enhanced fujita scale.The enhanced fujita scale was improved to original f-scale because it uses degree of damage indicators.
