With All That Sunlight Heat And Perfect Climate Why Hasn

Why aren't we overloaded with the Sun's energy on Earth?

Because the sun's energy is radiated into space at exactly the same rate at which it comes in, that's called equilibrium. The sun's energy when it reaches earth's atmosphere is approximately 1370 watts per square meter. Some of this gets reflected back into space, and only about 900 watts per square meter reaches the surface. When it reaches the surface, it goes through many different energy pathways of varying complexity, but eventually, it always ends up as heat. That heat warms the earth's surface and atmosphere, and that warm atmosphere radiates energy out into space. Now, the thing to remember is that only one side of the earth is exposed to the sun at a time. By contrast, all of the earth's surface is constantly radiating heat energy out into space. The warmer the earth is, the more energy it radiates outward. So, if we started with a very cold earth, the sun's energy would warm it up more and more until it got hot enough that it was radiating heat out as fast as it received heat. The rate at which the earth collects and radiates heat depends on a complex interplay of atmospheric composition, water, dust, weather, surface temperature, etc. If any of those change, then we come to a new equilibrium. For example, if the amount of carbon dioxide in the atmosphere increases, it becomes less effective at radiating heat away. That means that the balance is disrupted and the planet will absorb more heat than it loses, the temperature will rise, and that will cause it to radiate more heat, until equilibrium is reached again. That particular effect is called "the greenhouse effect", and is the reason that the planet is slowly warming right now.

Climatology: Why does the same interior temperature feel different in the summer or winter?

The response to seasonal change in temperature depends on what a person gets used to. This is called acclimatization, and the response is quite ideosyncratic.If you spend most of your time indoors and seldom brave the cold outside, your body will not acclimatize to the cold, rather, its comfort zone will remain a function of the thermostat setting for your abode. Any draft set in motion by the temperature differential between inside and outside air will give you a chill.If you spend a lot of time outdoors in the winter, your body will likely lower your physiological comfort zone in order to avoid a sweat upon exertion or when inside. This is partly due to wearing layers indoors, and partly to becoming acclimatized to the outdoors. In Salt Lake City I could shovel snow quite comfortably at 20 degrees F wearing only a hoodie and polyester sweat pants. When I came back inside to a 60 degree room I started to sweat profusely.Personally, I can’t stand the warm interior temperatures set for most American households and places of business during winter. And I throw open the windows of my apartment in winter quite frequently. This goes beyond acclimatization, it is a function of one’s own physiology. My body is set to prefer cool weather and warm clothes, with body heat keeping me in my comfort zone. I don’t feel uncomfortable walking around naked with my apartment temperature at 60 degrees F, but have to put on layers when sedentary for over an hour. I don’t think that response is commonplace in America, must be the Swedish in my bloodline.

Which countries in the world have summer all year round?

Countries located within the equator within 23° latitude of the earth will generally have “summer” all year long.In Indonesia, we have periodical weather changes, they are generally classified within dry season (April - September) and rainy season (September - April). And since climate is never a definitive thing, sometimes the rainy season starts at November / December or as late as January and ended somewhere in March or might be earlier. Otherwise, the weather at below 3.000 feet above sea level always varies between 26° at its coldest to 37° at the hottest.Our summer is not as hot as those in 4 seasons countries. Been there, lived through that, and people who live in tropical countries have no idea what kind of ideal weather they are currently living in. Our summer is characteristically mild, damp, and the warmness stays through the night. There is no breeze to soothe the heat, so if you sweat, you will drip until you are totally soaked.
