Local Weather Seasonal Change on Land and Water Drought
hello is me again. My location is San Jose, California America. this information might be useful to answer the question because I think the question ask lots of thing about the local weather.
This is the geography homework that need to answer all the question, no words limit, but need to answer the question thoughtfully
The writing requirement is the same as the previous one, do not need to be fancy, make it look like a college writing is good enough.
Follow is the question:
Seasonal Change on Land and Water, Drought
Background for sections 1 and 2
Why do we have seasons?
The short answer for this is the tilt of the earth.
The tilt causes an uneven distribution of sunlight energy (insolation) by latitude and time of year. Insolation, or INcoming SOLar radiATION is the focus of this lab. Insolation refers to the energy that is coming to Earth in the form of sunlight. This energy (or light) is measured in units of watts per meter squared or W/m2.
One way to think about insolation is to consider that the average amount of energy coming to Earth in July is roughly 300 W/m2. Imagine this as hanging three 100-watt light bulbs over every square meter of the earth. It is this energy that provides the basis for all life on Earth. The amount that arrives each day dwarfs the amount of energy that people produce with power plants.
In sections 1 and 2 we will visualize the insolation as a map. As you look at these visualizations of insolation consider the following:
Why does the energy vary by latitude?
The explanation for this has to do with how sunlight spreads over the spherical (and tilted) earth. Recall our discussion in lecture about the subsolar point and how it shifts with the seasons.
Why is the energy evenly distributed across the lines of latitude?
The answer is that the earth turning on its axis forms these lines, or this is averaged out over the day.
The relationship between insolation and surface temperature is the next thing that we will focus on. One thing that may be immediately clear to you is that while two locations such as San Francisco, CA and Wichita, KS have the same insolation (and are at about the same latitude), their temperatures are very different on a given day.
Why do two locations that receive the same insolation have different surface temperatures?
The answer lies in the heat capacity of the surface materials. While insolation is the primary cause for surface temperature, the heat capacity of the surface materials have an effect as well. Recall from lecture that land and water have different heat capacities. In other words, water can absorb much more heat energy before it heats up, while land heats and cools very quickly as it absorbs incoming solar radiation (insolation). Recall the example we discussed in lecture where the concrete around a pool will often be very hot, while the water remains cool, yet both have been subject to the same amount of insolation and both have absorbed the same amount of insolation. The reason the water is cool is that it is much more resistant to change. So over a very large area, the amount of land and water can have a large affect on regional temperatures. Most of the land on Earth is located in the Northern Hemisphere. Therefore, seasonal change in the Northern Hemisphere is more extreme than in the Southern Hemisphere.
Section 1: Understanding insolation distribution
Go to the University of Nebraska Daylight Hours Explorer (Links to an external site.)Links to an external site.. Under the Setting box on the right side of the screen, notice that you can adjust the latitude and the day of the year. Use this page to answer the following questions about the relationship between daylength, day of the year and latitude. Visually impaired students may instead use a screen-reader friendly page from US Naval obsevatory (Links to an external site.)Links to an external site. Use form B on this page. (3 points each)
1. 60 degrees North:
How many hours of daylight are received at 60 North on the summer solstice (June 21)?
How many hours of daylight are received at 60 North on the autumnal equinox (Sept. 23)?
How many hours of daylight are received at 60 North on the winter solstice (Dec. 22)?
2. 30 degrees North:
How many hours of daylight are received at 30 North on the summer solstice (June 21)?
How many hours of daylight are received at 30 North on the autumnal equinox (Sept. 23)?
How many hours of daylight are received at 30 North on the winter solstice (Dec. 22)?
3. Equator:
How many hours of daylight are received at the equator on the summer solstice (June 21)?
How many hours of daylight are received at the equator on the autumnal equinox (Sept. 23)?
How many hours of daylight are received at the equator on the winter solstice (Dec. 22)?
