Optional standard mileage rates for use of a vehicle will change a little for 2015, the IRS announced on Wednesday, with the business use rate going up and the medical and moving rate going down (Notice 2014-79).
Thunderstorms are caused by a collision of warm air and cold air. A thunderstorm is a cloud formation where large amounts of water undergoes a cycle of condensation, freezing then revaporizating as the currents of vapor within the cloud rises and falls. This produces static electricity which discharges as lightning. Thunderstorms are caused by a collision of warm air and cold air. A thunderstorm is a cloud formation where large amounts of water undergoes a cycle of condensation, freezing then revaporizating as the currents of vapor within the cloud rises and falls.
Thunderstorms are most likely to form when the temperature of the air decreases with height pretty rapidly; for example, when itâs hot at the ground and cold aloft. Thunderstorms that form at night occur in the absence of heating at the ground by the sun. Consequently, the storms that form at night are usually âelevated,â meaning that they form aloft above the cooler air near the ground, rather than near the ground, which only during the day can get warmer.
