Where does the sun rise?

Monday, July 29, 2019

The earth rotates around an imaginary axis in a counterclockwise direction.
This rotation causes our daytime and night time.

If you find a simple globe, turn off the lights, point a flashlight at the globe, and spin it counterclockwise will you will notice the following. As the earth rotates notice how the east coast of Australia moves into the sunlight first, and then notice the last part of Australia to receive sunlight is the west coast.

So in the morning when you look at the sun rising you are looking east.
In the evening when you see the sunset you are looking towards the west.

The sun rises in the east and sets in the west only two times a year in each hemisphere

In the northern hemisphere on March 20, which is the first day of spring also called the vernal equinox the sun rises due east. Moving forward the sun then starts setting more northeast. The sun continues to set a little more northeast each day until June 20 or 21 which is the first day of summer also called the summer solstice.  After the summer solstice, the sun starts setting less to the north until September 22 which is the autumn equinox or the first day of autumn on this day the sun sets due east again.

After this day it will rise a little further southeast until December 21 or 22 which is the first day of winter also called the winter solstice.

After this day it sets a little less south until  March 20, which is the spring equinox.
It takes one year to complete this cycle.

In the southern hemisphere,

  • The first day of spring is September 22
  • The summer solstice is between December 20-22
  • The autumn equinox is March 20 
  • The winter solstice is June 21st

How Hurricanes Form

Sunday, July 21, 2019

Hurricanes can be both beautiful and incredibly destructive
When a tropical cyclone reaches sustained winds of 74 mph, it is called a hurricane.
The official hurricane season is June 1 to November 30, but hurricanes sometimes occur outside of this season.
In the North Atlantic, and the central North Pacific, the term hurricane is used.
The same type of disturbance in the Northwest Pacific is called a typhoon.
Meanwhile, in the South Pacific and the Indian Ocean, the generic term tropical cyclone is used.

Hurricanes need the following ingredients in order to occur

A group of thunderstorms that move over the ocean

Warm moist water. In fact, the water needs to be 80 degrees or higher.
Also, this warm water needs to be about 200 feet deep

Unstable air that allows the moist air to rise  this rising air needs to be humid up to 18,000 feet
This large amount of water vapor supplies latent heat energy for the storm

Gentle winds in the upper atmosphere traveling at the same speed and direction to avoid ripping the storm apart

A high-pressure system in the upper atmosphere

Put all of these ingredients together and you may get a hurricane

Storms that form north of the equator spin counterclockwise. Storms south of the equator spin clockwise.

Indian Seat Day Hike-Sawnee Mountain

Sunday, July 14, 2019

This summer, my wife and I have found a new trail or park to explore each Friday. It has been a lot of fun and we have discovered some great parks.
One trail we discovered was the Indian Seat Trail.

Indian Seats Trail Loop is a 3.1-mile loop trail located near Cumming, Georgia that features beautiful views, winding trails, and a mix of hardwood and pine trees
The trail is rated as moderate.
The Indian Seats Trail eventually makes its way to the summit of Sawnee Mountain, which has outstanding long-range views of the North Georgia mountains.

The mountain is named after a local Cherokee Native American, Sawnee. 
The Sawnee Mountain Preserve Visitor Center is the ideal place to begin your visit to the Preserve. Hours of operation are Monday - Saturday, 8:30AM - 5:00PM.  Admission is free of charge. The Center features interactive exhibits a Mountain climbing wall and area, summer programs and much more.

There are three access points
4075 Spot Road
2500 Bettis-Tribble Gap Road
2505 Bettis-Tribble Gap Road

This area was once the site of abundant gold mining prospects back in the 1800s and you can see evidence of past gold mining.

If you have young children they can explore in a fort and then use the picnic tables for a nice lunch.
