The number of tornadoes recorded annually in North America has more than tripled since 1953. Yet meteorologists insist that the climatic factors affecting the creation of tornadoes are unchanged.

"Surprising" Phenomenon
Why have there been so many recorded tornadoes since 1953 if the climate has not made them any more likely to form?

Objective
Any hypothesis resolving this discrepancy must state a reason for tornadoes to have tripled despite the constant climatic factors. It will explain why tornadoes since 1953 are much more likely to be seen or give a reason for the actual number of tornadoes to have tripled.

A
The factors affecting the creation of tornadoes were not well known to meteorologists before 1953.
This does not explain the increase in recorded tornadoes. Meteorologists know those factors have not changed since 1953, regardless of whether they understood those factors in 1953.
B
The intensity of the average tornado is greater now than it was in 1953.
This introduces a new mystery without resolving the discrepancy at hand. A greater average intensity does not explain a greater number of tornadoes.
C
The number of tornadoes recorded annually has increased only slightly in the last five years.
This offers no reason why the number of recorded tornadoes has tripled since 1953. It does not address the period between 1953 and five years ago.
D
The amount of property damage done by tornadoes has grown substantially since 1953.
This does not explain why more tornadoes have been recorded since 1953. It is not stated that more tornadoes have destroyed property, only that the total damage caused by those tornadoes has been greater.
E
Many more citizens are helping authorities detect tornadoes now than in 1953.
This explains why the number of tornadoes recorded has tripled since 1953. More people are looking for tornadoes, making them more likely to be spotted, even if their overall numbers have not changed.
