air mass

Air mass storms generally are isolated, meaning you should be able to safely fly around them.

Since cold air is dense and sinks, while warm air is light and rises, a thermal circulation develops that favors an onshore breeze flowing from the cold air mass to the warm air mass.

There are six main types of air mass in total that each control temperatures and the level of humidity in the UK.

Polar maritime is the most common air mass to affect UK weather.

Second, it encloses the basin and consequently makes the WMB the source region of maritime Mediterranean air, which is a relatively warm and wet air mass that produces an intense air-sea heat exchange [24].

Such is the impact of the advancing spread of the Torrid climate belt and its associated moist air mass in response to warming and the consequent change of climate patterns.

Wednesday's weather is expected to be affected by yet another polar air mass accompanied by thunder and rain storms with hail from time to time.

However, the department anticipated that the situation would improve by the end of this month as the cold air mass from China is expected to meet the warm air mass in Thailand and cause rain nationwide.

"The north-west and west will have more cloud and a bit more moisture but the warm air mass is staying over Scotland."

After six weeks of uncommonly dry and moderate weather, "the coldest air mass so far this winter" is slated to arrive Saturday night from Alaska across much of the Pacific Northwest, cautions Steve Pierce, president of the Oregon chapter of the American Meteorological Society.

The security operation saw 1,400 frontline officers - one in six of all officers in the force - drafted in as more than 50,000 worshippers gathered for the open air mass on September 19.

The Pope is to start his four-day trip in Scotland where he will be received by the Queen at Holyroodhouse in Edinburgh before travelling to Glasgow for an open air Mass.

In the 1980s, the hot wire air-mass meter was developed to measure air mass using thermal measurement principles and was used in Formula 1 racing.
