A stratus cloud is any low-lying cloud that makes the atmosphere hazy2. Like all clouds, they are formed when water vapour3 condenses4 when it rises to a cooler part of the earths atmosphere. However, a fog is different because the water vapour reaches its dew point (the temperature at ...
in what scientists sayis the result of unusually low temperatures in the atmosphere above the north pole.The hole, which has been tracked from space and the ground over the past few days,has reached record dimensions, but is not expected to pose any danger to humans unless itmoves further ...
Full of or covered with clouds; overcast. Fog A thick cloud of tiny water droplets suspended in the atmosphere at or near the earth's surface which obscures or restricts visibility (to a greater extent than mist; strictly, reducing visibility to below 1 km) The collision occurred in thick ...
Thunderstorms Usually occur in summer, when a cold front forces warm, moist air to rise rapidly Cumulus clouds build up to form cumulonimbus clouds from these, heavy rain or hail falls Thunderstorms Lightning occurs when a cloud discharges electricity the current causes the air to heat and expand...
In spring, fog can be a good thing in the form of low clouds which hold in heat and reduce chances for frost. It is in spring that we should pay even more attention to fog if we are growing plants for food or enjoyment. Fog forming early in low areas is a bad sign if you are ...
An alternative explanation is based on the way that thunderstorms on Earth can generate electron beams in the upper atmosphere. While regular lightning bolts travel between clouds and the ground below, high-energy particles streaming from space called cosmic rays can trigger electron...
When liquid water evaporates, it becomes water vapor and enters the atmosphere. This process is essential to kickstart the water cycle, a continuous movement of water on, above and below the surface of the Earth. Evaporation occurs when heat from the sun causes water from oceans, rivers, ...
the lower pressure area, heats up, and rises, in turn, producing swirls in the air,according to NASA. Once this hot air gets high enough into the atmosphere, it cools off and condenses into clouds. Now, the growing, swirling vortex of air and clouds grows and grows and can become a ...
What is lightning that occurs below the horizon or behind clouds called? Lightning Lightning is a naturally occurring phenomenon that releases one gigajoule of energy because of electrostatic discharge. There are three types of lightning: cloud to ground, cloud to air, and cloud to cloud. ...
“The ash itself is short-lived in the atmosphere because it’s heavy, it’s big and it tends to settle out quickly,” Huey told CNN. It’s the gases that are able to reach much higher in the atmosphere. Dense ash near the surface creates hazardous air quality and...
