Thermometers and rain gauges are used to collect weather data. These days temperatures are also taken by satellites to reduce the possibility of false high readings due to heat in cities.
What are the 3 measures that define a climate?
The simplest way to describe climate is to look at average temperature and precipitation over time. Other useful elements for describing climate include the type and the timing of precipitation, amount of sunshine, average wind speeds and directions, number of days above freezing, weather extremes, and local geography.
How are climate variables measured?
Thermometers, shielded from direct solar energy, are used to measure surface air temperature. The most common type of thermometer is the liquid-in-glass thermometer. More precise thermometers measure air temperature by checking how much electricity can pass through a sample of pure metal.
What are the different scales of climate?
Climate Cycles at Multiple Scales scales, operating at multi-millennial, millennial, century, decadal, and interannual scales (Figure 1), and caused by independent physical mechanisms.
Climate is determined by the atmospheric circulation and by its interactions with the large- scale ocean currents and the land with its features such as albedo, vegetation and soil moisture.
What are the key terms of climate change?
Global warming vs climate change Global warming is an increase in the Earth's average surface temperature from human-made greenhouse gas emissions. On the other hand, climate change refers to the long-term changes in the Earth's climate, or a region on Earth, and includes more than just the average surface temperature.
