Measuring Temperature Using A Thermometer
A demonstration of how to measure the air temperature using a thermometer. There are temperature differences between day and night, and the temperature varies between shade and full sunshine. We can describe the temperature as being hot, mild, chilly or freezing.
- This clip is from:
Children could measure the temperature in different areas of the school. What things affect the temperature? Where would be the best place to go and cool down? Children could record their findings in a table. They could also set up a camera to take pictures of the thermometer throughout the night. They can then compare the mean, median, mode and range of the temperatures in and around the school.
Temperature Inversion: Meaning Types And Significance
In this article we will discuss about:- 1. Meaning of Temperature Inversion 2. Types of Temperature Inversion 3. Significance.
Meaning of Temperature Inversion:
Temperature decreases with increasing altitudes in the troposphere at an average rate of 6.5°C per 1000 metres but sometimes this normal trend of decrease of temperature with increasing heights is reversed under special circumstances i.e., temperature increases upward upto a few kilometres from the earths surface. This is called negative lapse rate.
Thus, warm air layer lies over cold air layer. This phenomenon meteorologically is called inversion of temperature. Such situation may occur near the earths surface or at greater height in the troposphere but the inversion of temperature near the earths surface is of very short duration because the radiation of heat from the earths surface during daytime warms up the cold air layer which soon disappears and temperature inversion also disappears.
On the other hand, upper air temperature inversion lasts for longer duration because the warming of cold air layer aloft through terrestrial radiation takes relatively longer period of hours.
Types of Temperature Inversion:
Inversion of temperature occurs in several conditions. Sometimes, it occurs at ground surface while some times, it occurs at greater height. Sometimes, it is caused in the static atmospheric conditions while some times, it occurs due to horizontal or vertical movement of air.
Tropical And Temperate Region
The tropical zone has a temperature of 65-degree F or above. The tropical region is also referred to as tropical or the torrid zone. While, in the temperate region, there is a variation in temperature which is not extreme of cold nor of hot. This region lies between the equator and the pole.
The tropical regions are the area of the Earth which is between the Tropic of Cancer and the Tropic of Capricorn, from the latitude lines 23.5 degrees north and south of the equator, respectively. While the temperate regions are between the subtropical and the polar regions.

Climate Change: Global Temperature
- Earths temperature has risen by 0.14° F per decade since 1880, and the rate of warming over the past 40 years is more than twice that: 0.32° F per decade since 1981.
- 2020 was the second-warmest year on record based on NOAAs temperature data, and land areas were record warm.
- Averaged across land and ocean, the 2020 surface temperature was 1.76° F warmer than the twentieth-century average of 57.0°F and 2.14F warmer than the pre-industrial period .
- Despite a late-year La Niña event that cooled a wide swath of the tropical Pacific Ocean, 2020 came just 0.04 Fahrenheit shy of tying 2016 for warmest year on record.
- The 10 warmest years on record have occurred since 2005.
- From 1900 to 1980 a new temperature record was set on average every 13.5 years from 19812019, a new record was set every 3 years.

Given the tremendous size and heat capacity of the global oceans, it takes a massive amount of heat energy to raise Earths average yearly surface temperature even a small amount. The roughly 2-degree Fahrenheit increase in global average surface temperature that has occurred since the pre-industrial era might seem small, but it means a significant increase in accumulated heat.
Past And Future Change In Global Temperature
Though warming has not been uniform across the planet, the upward trend in the globally averaged temperature shows that more areas are warming than cooling. According to NOAA’s 2020 Annual Climate Report the combined land and ocean temperature has increased at an average rate of 0.13 degrees Fahrenheit per decade since 1880 however, the average rate of increase since 1981 has been more than twice that rate.
Based on NOAA’s global analysis, the 10 warmest years on record have all occurred since 2005, and 7 of the 10 have occurred just since 2014. Looking back to 1988, a pattern emerges: except for 2011, as each new year is added to the historical record, it becomes one of the top 10 warmest on record at that time, but it is ultimately replaced as the top ten window shifts forward in time.

Bergeron And Spatial Synoptic
The simplest classification is that involving air masses. The Bergeron classification is the most widely accepted form of air mass classification. Air mass classification involves three letters. The first letter describes its moisture properties, with c used for continental air masses and m for maritime air masses . The second letter describes the thermal characteristic of its source region: T for tropical, P for polar, A for Arctic or Antarctic, M for monsoon, E for equatorial, and S for superior air . The third letter is used to designate the stability of the atmosphere. If the air mass is colder than the ground below it, it is labeled k. If the air mass is warmer than the ground below it, it is labeled w. While air mass identification was originally used in weather forecasting during the 1950s, climatologists began to establish synoptic climatologies based on this idea in 1973.
Based upon the Bergeron classification scheme is the Spatial Synoptic Classification system . There are six categories within the SSC scheme: Dry Polar , Dry Moderate , Dry Tropical , Moist Polar , Moist Moderate , and Moist Tropical .

Global Temperature In 2020
According to the 2020 Global Climate Report from NOAA National Centers for Environmental Information, every month of 2020 except December was in the top four warmest on record for that month. In December, the presence of a moderately strong La Niña event cooled the tropical Pacific Ocean and dampened the global average warmth. The month turned out as “only” the eighth warmest December on record.
This animation shows maps of monthly temperatures for JanuaryDecember 2020 compared to the 19812010 average, with warm anomalies in red and cool anomalies in blue. The final frame of the animation shows the 2020 average. Note that the temperature range on the monthly maps is broader than the range for the annual average .
Despite La Niña, 2020 ranked as the second-warmest year in the 141-year record for the combined land and ocean surface, and land areas were hottest on record. Many parts of Europe and Asia were record warm, including most of France and northern Portugal and Spain, most of the Scandinavian Peninsula, Russia, and southeastern China. An even larger portion of the globe was much warmer than average, including most of the Atlantic and Indian Oceans. The heat reached all the way to the Antarctic, where the station at Esperanza Base, at the tip of the Antarctic Peninsula, appeared to set a new all-time record high temperature of 65.1 degrees Fahrenheit on February 6, 2020.
Which Countries Are In The Temperate Zone
4.1/5Countries that lie in the temperate zone are as follows:
- United States of America.
This type of climate is normally located along leeward lower east coast continents such as in southeast and central Argentina, Uruguay and south of Brazil, the southeast portions of east Asia, the southern United States, South Africa, and eastern Australia.
Likewise, what is temperate zone in geography? the part of the earth’s surface lying between the tropic of Cancer and the Arctic Circle in the Northern Hemisphere or between the tropic of Capricorn and the Antarctic Circle in the Southern Hemisphere, and characterized by having a climate that is warm in the summer, cold in the winter, and moderate in the spring and
Regarding this, where is the temperate zone?
In broadest sense, the temperate zone encompasses the areas of Earth that lie between the tropical zone and the polar zones. The temperate zone is sometimes called the mid-latitudes because they exist roughly between 30 degrees and 60 degrees north and south latitude.
What happens in the temperate zone?
In geography, temperate latitudes of the Earth lie between the subtropics and the polar circles. Average yearly temperatures in these regions are not extreme, not burning hot nor freezing cold. Temperate means moderate. Unlike in the tropics, temperatures can change greatly here, between summer and winter.

Demography Fauna And Flora
The vast majority of the world’s human population resides in temperate zones, especially in the northern hemisphere, due to its greater mass of land. The biggest described number of taxa in a temperate region is found in southern Africa, where some 24,000 taxa have been described, but the native fauna and flora of this region does not have much cultural importance for the majority of the human population of the world that lives in the Temperate Zones of the Northern Hemisphere, only environmental importance.
