However, te basic principles remained the same but techniques changed dramatically over the past few decades. Een in the modern age of the 21st century, wather experts are measuring rainfall in millimetres and centimetres. Te main idea of scientific development is to minimize the level of human effort needed to get the job done. Te concepts remain the same and means of applying them change as world clock moves forwards (Kemp, 1994). Te conventional methods of measuring rainfall were crude and these were more prone towards experience human climatologists faced significant difficulties in terms of issuing flood warnings and they had limited geographical coverage and therefore, te estimates were inaccurate most of the times.
Te manual systems of measuring rainfall had to be replaced with mechanical and computerized ones so that the accuracy of measurements can improve and therefore, te quality of decision making can also be enhanced. Tchnological intervention in the featured field have minimized dangers to human life and taken off the burden of measuring rainfall manually from the shoulders of climatic experts. Sme of used to measure temperature will also be discussed in the following section: -hermocouples are temperature measuring devices and they usually consist of two different conductors that are contacted with each other on at least one point.
Te device is known to generate a specific level of voltage whenever there is a significant difference in the temperature level of one point from that of another which used as a reference. Termocouples are the most applied instrument to measure temperature. Tey also have the limited potential to convert temperature gradient electricity experts in alternative sources of energy are very interested in applying the method used by thermocouples to produce electricity on a vast scale.
Tese instruments are cost effective and have the ability to gauge temperature in more than one environments. Tey are usually powered with battery and therefore do not require to be connected to external power source in order to function (Wrbanek, Falick, &Zhu, 2012). Hwever, tey are less accurate and less reliable as well and because of these reasons, pofessionals do not apply them and are applied get a rough idea of temperature levels in multitude of situations.
Te digital thermocouples conventionally measure temperature in Celsius with a.. .
