Knowing cloud base is useful for anyone who practices various wind sports and outdoor activities in the air, such as paragliding, parachuting, air ballooning and different types of aviation. This device reflects rays of laser from the base of the clouds and calculates the travel time to it. The base of the cloud is measured with an instrument called "ceilometer" or a type of atmospheric lidar, the working principle of which is based on the laser. (Sometimes cloud base is also measured in hectopascal (hPa), as the pressure level corresponding to the altitude of the base of the cloud.) In other words, the cloud base parameter in your weather forecast answers the question of how high the clouds are from the earth, if you count to their base. Therefore, the base is most often measured in the same way as, for example, the height of mountains - in meters above sea level, feet, or other units in your region. The cloud base or the base of the cloud is the height of the lowest visible part of the cloud. Clouds form in the sky because the air becomes saturated with moisture when it cools to the dew point, or when much water evaporates from the earth's surface and water vapor forms. What is cloud base?Ī cloud is the tiny liquid particles of water vapor, frozen water crystals, and other particles suspended in the air. Learn what the cloud base is, why you may need it, how else do we measure clouds, and how to use it all for your outdoor activity. If you haven't tried this or other air sports yet but want to do, this article is right for you. Of the 16 new locations, six are actively issuing tickets, six are issuing warnings and the rest aren't ticketing at all yet, but will be within weeks.Cloud base is a well-known weather parameter for outdoors enthusiasts who engage in a various wind sports in he air - for example, paragliders but not only them. However, the map only shows cameras actively ticketing drivers. A city map online shows the locations of the city's 162 speed cameras - all by parks and schools. There are warning signs at all speed camera locations. The city doesn't give information that they are relocating these cameras to another location." "Most people are not gonna know that the cameras are moved to a different location because the city does not provide that information, it's not transparent. "They absolutely are catching people off-guard," said Mark Wallace, who runs Citizens to Abolish Red Light Cameras. While some welcome moving cameras to areas that may need them, others are concerned that more drivers could rack up tickets, not knowing about the cameras being shuffled. I-TEAM REPORT | Chicago speed camera ticket violations spike since city changed speeding law I-TEAM REPORT | Group says Chicago's new speed camera law unfairly impacts minority drivers "It's been plenty of accidents and there's constantly racing up and down 83rd Street," he said. There have been 15 fatal crashes here in a recent three-year period. He hopes the new speed camera will reduce crash numbers near Avalon Park on East 83rd Street. "It slows down a lot of the traffic and it's kids around here, it's a park, so I like it, personally," Corwin Gillespie told the I-Team. There is also a way to check if there is a new camera on your block. We dug into crash and accident data to uncover why. With 162 speed cameras spread throughout the city of Chicago, the I-Team uncovered that 16 cameras were moved to new locations.
