Seismology
A sun recorder is a weather instrument that records the number of minutes or hours per day in which the sun's rays are present to the degree capable of burning through a paper recording strip, when magnified through a glass sphere.
The temperature on Mars is not often recorded so it is hard to say what the coldest temperature is. However, scientists know that Mars can reach a daytime high of around 70 degrees but with no atmosphere to hold in heat, the temperature frequently drops to -225 degrees.
Global records are not available and only U.S. records can easily be found. Those records show 1,103 tornadoes for the U.S.
Since official records began in 1950 the U.S. has recorded approximately 61,000 tornadoes. Records prior to that are more difficult to track down. Similarly, records for other countries are incomplete.
That is unknown. Current records indicate at least 1800 on average, but the number is almost certainly higher as many countries do not keep records of their tornadoes.
