This may sound confusing at first, but keeping time this way offers a lot of benefits to people, companies, and even the military around the globe. However, if the countries are located West or East of each other, they will observe a different time – this is why Spain and Russia, as an example, are in different time zones despite being much closer than Spain is to South Africa. What this means is that it’s noon everywhere along the same longitude: it’s the same time in Madrid and Cape Town, despite these cities being thousands of miles away from each other. This is because, once again, the Earth rotates around its axis, but the poles do not move. Now, time zones are calculated by degrees West or East rather than North or South. This way, it’s 12PM at noon everywhere in the same time zone. Each slice is a time zone that is 15, 30, 45, and so on degrees West or East from Greenwich one slice accounts for one hour behind or ahead the Greenwich Mean Time ( GMT), which sits atop the zero longitude. To keep track of time around the world accurately, scientists split the planet into 24 slices, each slice accounting for 15 degrees of longitude counting from the Greenwich Meridian, also known as longitude zero. When it’s evening in London or Frankfurt, the sun is only rising in Lima or Los Angeles in other words, different regions of the world observe noon at a different time, and when it’s night in one region, it may be noon in another. Because the Earth is a sphere that rotates, it cannot be noon at the same time all over the world: as the Earth turns, the sun hits different regions at different times. To start at the beginning, let’s explain what a time zone really is. Ready to start keeping world time? Let’s dive right in: And to make time zones more fun, we’ll list some curious time zone facts and trivia at the end of the article, so be sure to read it till the end. Next up, we will provide a list of the major territories that are located in the CDT time zone, as well as all the major cities in this region. To clear up the confusion about time zones, explain CDT (Central Daylight Time), one of the major time zones in the world, we’ll dig into the science and history behind time zones and talk about how it works. Knowing how time zones work and how to calculate time in different locations around the planet helps you plan and communicate better – after all, no one wants to get a work call or a Zoom invitation for midnight or two in the morning, even though it may be a perfectly reasonable time on your end!

Your input will greatly assist others in teaching the "hows" and "whys" of weather. We welcome your feedback on this project. You are free to use the materials in any manner you wish. Interspersed in JetStream are "Learning Lessons" which can be used to enhance the educational experience. The information contained in JetStream is arranged by subject, beginning with global and large-scale weather patterns followed by lessons on air masses, wind patterns, cloud formations, thunderstorms, lightning, hail, damaging winds, tornados, tropical storms, cyclones, and flooding.

As the winds are diverted around the high areas, turbulence is created, and the disturbance in the flow continues downstream in the form of rows of vortices that alternate their direction of rotation. In this case, driving wind rushes past the tall peaks on the rugged Canary Islands.
