We All know that the inhabitants of the globe live in very different climatic zones. That is why with the onset of cold in one hemisphere starts warming in the other. Many go on vacation to bask under the sun in other countries and do not even think about the annual amplitude of temperatures. How to calculate this indicator, children learn more from school. But with age often just forget about its importance.
Before you can calculate the annual amplitude of temperature according to schedule, you need to remember that this is a definition. Thus, the amplitude itself is determined as the difference between the maximum and minimum rate. When you calculate the annual temperature amplitude will serve as the thermometer reading. For accurate results it is important that the thermometer was always used only one. This will allow yourself in a specific region determine the schedule level temperatures. How to calculate annual amplitude in climatology? Experts use the average readings monthly temperatures over the years, so their figures are always those computed independently for their settlement.
So, before you calculate the annual amplitude of air temperature, you must consider several important factors influencing its performance.
In the first place, this latitude of the required point. The closer the region is to the equator, the lower will be the annual fluctuation of temperature. Closer to the poles of the globe the continents feel the seasonal change of climate is stronger and, consequently, the annual amplitude of the temperatures (how to calculate - further in the article) will proportionally increase.

Also on the performance of air heating is also influenced by the proximity of the region to large bodies of water. The closer the sea, ocean or even a lake, the climate is milder, and the temperature change is not as pronounced. On land the temperature difference is very high, moreover, both annual and diurnal. Of course, to change such a situation can often come from the sea air masses, as, for example, in Western Europe.
Depends on the amplitude of the temperature and the altitude above sea level. The higher is the required point, the smaller will be the difference. With every kilometer it is reduced by approximately 2 degrees.
Before you can calculate the annual amplitude of temperatures we need to take into account seasonal climatic changes. Such as monsoons or drought.
To Carry out such calculations every owner of a thermometer and the free time can own. To obtain maximum accuracy for a specific day, you should record readings of the thermometer every 3 hours, starting at midnight. Thus, from the obtained 8 measurements it is necessary to allocate the maximum and minimum rates. After that, more subtracted from less and the result is the daily amplitude of the specific day. So calculations are made at the weather station specialists.
It is Important to remember a basic rule of mathematics that two negatives make a positive. That is, if the calculations are performed in the cold season, and daily temperature ranges from a positive day to a negative night, the calculation would look like this:
+5 - (-3) = 5 + 3 = 8 &- circadian amplitude.
The Calculations to determine annual variations in the readings of the thermometer are made similarly, only the maximum and the minimum value is taken average readings of thermometers the hottest and the coldest months of the year. They, in turn, are computed by obtaining average daily temperatures.
To determine average readings for each day, you need to put in a number of all readings are recorded over a given period of time, and dividing the result by the number of stacked values. Get maximum precision when calculating the average of a larger number of measurements, but often enough removing the data from the thermometer every 3 hours.
Similarly, is calculated to a daily average computed and average temperatures for each month of the year.
Before you determine the annual amplitude of air temperature in specific region, you should find the maximum and minimum average monthly temperature. From more you need to take less, given the rules of mathematics, and the result is considered the most the desired annual amplitude.
In Addition to calculating the air temperature for various geographical purposes, the temperature difference between the important and in other Sciences. So, paleontologists are studying the activity of extinct species, by calculating the amplitude of temperature fluctuations in the whole centuries. They help different samples of soils and other methods of thermography.
Exploring the work of internal combustion engines, experts determine the periods as time intervals constituting fractions of seconds. For precision measurements in such situations, apply specific loggers.
In the geography of change of temperature can also be recorded in fractions, but this requires a thermograph. Such a device is a mechanical device, continuously fixing the temperature data to tape or digital media. He also determines the amplitude of the changes, given the exhibited time intervals. These precision instruments are applied in areas which were off limits to man, for example, in the areas of nuclear reactors, where every fraction of a degree, and follow their changes constantly is necessary.
From the foregoing it is clear how to determine the annual amplitude of temperature, and why the need for these data. Experts to help share the atmosphere of the entire planet to certain climatic zones. It is connected with the fact that the range of temperatures across the planet is so broad that to determine the average for it, which would be in fact, impossible. Division of climate in the Equatorial, tropical, subtropical, temperate continental and marine allows you to create a more realistic picture taking into account all factors influencing the temperature in the regions.
This separation of zones can be determined that the amplitude of temperature increases as a function of the distance from the equator, proximity to large bodies of water, and many other conditions, including summer and winter solstice. Interestingly, depending on the type of climate change duration and transition seasons as well as the peaks of hot and cold temperatures.
