Weather for Kids - Chapter 5 - Weather and Climate
Welcome to Teaching Weather for Kids
Before going forward with Weather for Kids Chapter 5, here are the answers for the trivia questions in Chapter 4 - "Weather, Tornadoes, Hurricanes and Lightning"
- Q: What are the defining characteristics of a thunderstorm?
A: Lightning, thunder, and intense winds.
- Q: What makes a tornado funnel cloud visible?
A: What we see as a funnel cloud is the condensing moisture inside the low-pressure zone along with the dust and debris picked up by the intense winds.
- Q: What gives a hurricane or typhoon its energy?
A: The storm gains energy and intensity as the low-pressure center travels over hundreds of miles of warm, open ocean water.
Chapter 5: Weather and Climate
In this chapter we will discuss:
After the TV weather person makes their report and prediction on the local station, many times there will be a short clip about the climate, often with dire warnings of how changes are going to mess everything up and that it is all mankind's fault. You may have heard people say things like “The weather is going to be exceptionally hot today, it must be because of global warming” or “We had a really bad winter last year because of climate change”.
These statements can be confusing because weather and climate are related, but they are not the same thing. On the NASA Climate page, it says that “The difference between weather and climate is a measure of time”, and even that is not quite accurate. Comparing weather and climate is not like comparing apples and oranges, nor is it like comparing an orange to a crate full of oranges. It is more like comparing oranges to fruit. In other words, oranges are fruit, and there are many fruits that have a lot in common with oranges, but not all fruit is like an orange.
Weather is an important part of climate, and when we classify climates one of the important things to look at is the average weather over an extended period of time. The climate of a certain region is generated by the interaction of five worldwide components: the atmosphere where weather is generated, the hydrosphere which is the mass of water found on, below and above the planet, the cryosphere or regions of solid ice such as the polar caps, the lithosphere or rocky outer shell of the planet, and the biosphere or the living things on the planet.
The most common way of classifying climates is using the Köppen Climate Classifications. The classifications were first published in 1884 and have been modified several times since. They were originally based on the notion that native vegetation is the best expression of climate. The system is divided into five main groups (A, B, C, D, E) and each group is further divided into types. Each climate type may be represented by a 2-4 letter symbol. For example, Miami has an Am or Tropical monsoon climate; Denver has a BSk or Dry Steppe climate with at least one month of average temperatures below freezing, Los Angeles has a Csa or Mediterranean climate with hot and dry summers dominated by subtropical high-pressure systems, and Chicago has a Dfa or Continental climate with the warmest month averaging greater than 72°F. Group E climates are polar and alpine zones
The Köppen climate classifications are useful for travelers and geography students as well as those studying weather and climate. There will be a more detailed breakdown of the Köppen climate in WeatherStationary's Knowledge Center.
Paleoclimatology is the study of ancient climates and weather patterns before modern record keeping. We know that the worldwide climate has changed many times, just like it is changing now. There are many theories and reasons behind climate change ranging from an “end of the world” scenario caused by pollution and other manmade factors to a natural cycle that would occur no matter what man does. This is not a forum to debate the various causes of climate change, let alone fix blame. We will just point out that climate change is happening, it has happened before, and species and civilizations who can adapt will survive and thrive.
- What are the five world-wide elements of climate?
- What expression of climate are the original Köppen climate classifications based on?
- What can the study of paleoclimatology teach us about climate change today?
(You'll get the answer in Weather for Kids Chapter 6 - to be published next week)
