Climate.... how much do you know about them~

Climate, is about a long-term trend of the weather over a long period of time. The elements of weather plays an important role of how the world's climates are classified into. there are 3 types of climates:
1. tropical
2.temperate
3. polar
  these three climates are distributed differently on the map.
For the tropical climate:
latitude- near the equator, between tropic of cancer (23.5degrees N), tropic of caricorn (23.5 deg S).
characteristics-temp:20-30 degC throughout, high rainfall, 1000-2000mm annual rainfall.
the reason why the its hotter in a tropical climate, is because, the countries are at the equator, so when the sun rays strike the earth's surface, sun rays are concentrated over a small area, thus heat is more intense.

temperate climate:
latitude- betwwen tropic of cancer and arctic circle, between tropic of capricorn and antarctic circle.
characteristics- 4 seasons in 1 year, temp: 34degC, winter, below 0degC ( not constant ), moderate rainfall, 300-1000mm annually.
 in a temperate climate, precipitation and temp fluctuate a lot, unlike the tropical climate.

polar climate:
latitude-between arctic circle and north pole, between antarctic circle and south pole.
characteristics- 4seasons in a year, temp: summer ( below 0degC), winter:( lowest of -89.2degC) , low rainfall of 110 mm annually, when N.hemisphere tilts towards the sun, 24 hours of sunlight at N.pole while the S.pole is in total darkness!


The question Ms J asked was can climate changes fluctuate in the same way weather conditions vary daily?
Now, heres my answer :
  Well, weather changes on a daily basis/hourly basis, but climate is the weather trends over a long period of time. thus, climate changes cannot fluctuate in the same way because it remains consistent for decades maybe even centuries. So, nope, it cant. climate changes cant change and vary like the weather conditions.
