![]() ![]() If clouds are made up of particles, then they must have weight and density.īut why do clouds float? The density of the same volume of cloud material is less than the density of the same amount of dry air. Since air has weight, it must also have density, which is the weight for a specific volume, such as a cubic inch or cubic meter. A barometer and air pressure will tell us that air does have weight! At sea level, the weight (pressure) of air is about 14 ½ pounds per square inch (1 kilogram per square centimeter). If all the water in the atmosphere rained down at once, it would only cover the globe to a depth of 2.5 centimeters, about 1 inch.ĭo you think clouds have any weight? How can they, if they are floating in the air like a balloon filled with helium? If you tie a helium balloon to a kitchen scale it won't register any weight, so why should a cloud? To answer this question, let's explore first if air has any weight. That may sound like a lot, but it is only about 0.001 percent of the total Earth's water volume of about 332,500,000 mi 3 (1,385,000,000 km 3), as shown in the table below. One estimate of the volume of water in the atmosphere at any one time is about 3,100 cubic miles (mi 3) or 12,900 cubic kilometers (km 3). Clouds are, of course, the most visible manifestation of atmospheric water, but even clear air contains water - water in particles that are too small to be seen. About 90 percent of water in the atmosphere is produced by evaporation from water bodies, while the other 10 percent comes from transpiration from plants. ![]() Strong winds move the clouds around the world until the water falls as precipitation, replenishing the earthbound parts of the water cycle. Cooler temperatures aloft allow the vapor to condense into clouds. Evaporation and transpiration transform liquid water into vapor, which ascends into the atmosphere due to rising air currents. Although the atmosphere may not be a great storehouse of water, it is the superhighway used to move water around the globe. The water cycle is all about storing water and moving water on, in, and above the Earth. Surface runoff The atmosphere is full of water.In 2021, they sold the 25-story, 294-unit Motion at Dadeland apartment building at 8400 South Dixie Highway for $114 million to Lerner Enterprises. This isn’t the first time 13th Floor, Adler and Barings are partnering. Global financial services firm Barings is a partner on the Link at Douglas project, according to media reports. Miami-based Adler includes a development services division that helps with land purchases, market analyses and master planning, and a property management division, according to its website. This year, 13th Floor also launched a $300 million investment fund targeting growing markets, especially in the Sun Belt, and distressed opportunities that may arise from high interest rates. The firm’s recent plans include a proposal for an apartment building with up to 350 units just south of the Brightline station in Ojus. “It’s an adjustment to the new world we live in,” he said.įounded in 2008, Miami-based 13th Floor has more than $3.5 billion of real estate under management, according to its website. The office space will be part of Tower 3. That is one-third of the previously planned 75,000 square feet that would have been traditional offices with long-term leases, according to Stolear. The developer now wants to build 25,000 square feet of offices and design the space for coworking. The new design also spaced out the towers to allow for “better view corridors” at the development. Overall, the project’s square footage didn’t really change that much, Stolear said. And the heights were decreased in part because the new design calls for apartments in Tower 3 to reach the ground floor on the east side of the building, and run along the garage podium on the west side of the building, Aaron Stolear, vice president at 13th Floor, told The Real Deal. Several one-bedroom apartments were combined into three-bedroom units, explaining the drop in the unit count. The developer proposes 815 units combined at both buildings, down from their previous plan for at least 850 apartments. 13th Floor wants Tower 3 to rise 36 stories and Tower 4 to reach 37 stories, down from the original plan for 39 floors for both buildings, according to a submittal to Miami-Dade filed last week. ![]()
