Weather Instruments and Measurements

The video tutorial explains the difference between weather and climate, highlighting how weather refers to short-term atmospheric conditions in a localized area, while climate is the average atmospheric conditions over a long period and large area. It also covers various weather instruments like thermometers, rain gauges, barometers, hygrometers, and anemometers, explaining their functions and how they measure different atmospheric elements. Additionally, the video discusses isolines such as isohyets and isotherms, which are used in meteorology to represent areas of equal rainfall and temperature on maps.

What is the main difference between weather and climate?

• Weather and climate are the same and can be used interchangeably.

• Weather changes daily and is localized, while climate is the average atmospheric condition over a long period.
