The table on the right shows the Accumulated Cyclone Energy for each storm in the season. The ACE is, broadly speaking, a measure of the power of the typhoon multiplied by the length of time it existed for, so typhoons that lasted a long time (like Typhoon Paka) have higher ACEs. The total ACE for the 1997 season was 594.11, which is the highest ACE for any tropical cyclone season in recorded history. This was because 11 of the 33 storms in the season reached super typhoon status. ACE for Linda, Paka, and Oliwa only include ACE during the time they were in the Western Pacific Basin.

Famous quotes containing the words accumulated, energy and/or ranking:
“Not many appreciate the ultimate power and potential usefulness of basic knowledge accumulated by obscure, unseen investigators who, in a lifetime of intensive study, may never see any practical use for their findings but who go on seeking answers to the unknown without thought of financial or practical gain.”
—Eugenie Clark (b. 1922)
“After the planet becomes theirs, many millions of years will have to pass before a beetle particularly loved by God, at the end of its calculations will find written on a sheet of paper in letters of fire that energy is equal to the mass multiplied by the square of the velocity of light. The new kings of the world will live tranquilly for a long time, confining themselves to devouring each other and being parasites among each other on a cottage industry scale.”
—Primo Levi (1919–1987)
“We should spend less time ranking children and more time helping them to identify their natural competencies and gifts and cultivate these. There are hundreds and hundreds of ways to succeed and many, many different abilities that will help you get there.”
—Howard Gardner (20th century)
