What is the meaning of mean temperature?

The average temperature of the air as indicated by a properly exposed thermometer during a given time period, usually a day, a month, or a year. For climatological tables, the mean temperature is generally calculated for each month and for the year.

How do you read high and low temperatures?

The forecast high is the highest temperature expected to occur that day, which in most cases is in the afternoon. The forecast low is the lowest temperature expected to occur during the next overnight period and on the vast majority of days will occur around daybreak the following morning.

How far back does temp go?

The temperature record of the past 1000 years describes the reconstruction of temperature for the last 1000 years on the Northern Hemisphere. A reconstruction is needed because a reliable surface temperature record exists only since about 1850.

What’s the normal temperature?

98.6°F
The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the “normal” body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness.

What time does minimum temperature occur?

When are the maximum and minimum temperatures likely to occur during the day? Answer: The maximum temperature of the day occurs generally in the afternoon while the minimum temperature occurs generally in the early morning.

When did thermometers become common?

However, by 1835 Becquerel and Breschet were able to establish the mean temperature of a healthy adult to be 37 °C (98.6 °F). By the 1860s, the use of the thermometer had become more common, and the physiological significance of body temperature was becoming clearer.

What was the average temperature in 2000?

Despite the overall increase, global temperatures have not climbed steadily during the decades. The average global annual temperature hovered around 13.7 °C (56.7 °F) from the 1880s through the 1910s….Temperature Change Since 1880.
