Question

Which two properties characterize an air mass?

Answer 1

Hint: An air mass is a volume of air characterised by its temperature and water vapour concentration in meteorology. Air masses may travel hundreds of kilometres and adapt to the features of the land underneath them. They're categorised by latitude and whether they come from a continental or marine source. Warmer air masses are referred to as tropical, whereas colder air masses are referred to as polar or arctic.

Complete Step By Step Answer:
Maritime and monsoon air masses are wet, whereas continental and superior air masses are dry. Weather fronts divide air masses with varying densities (temperature and moisture content). Once an air mass has moved away from its source, underlying vegetation and water bodies can swiftly change the character of the air mass. The properties of an air mass, as well as their change, are addressed by classification schemes.
The enormous quantities of air that make up air masses.
They are crucial to environmental research because they can forecast the weather that future air masses may bring.
Humidity and temperature are the most important factors in determining their major characteristics.
If there is a lot of humidity, it will either rain or snow in a certain region.
Warm masses indicate that it will be hot, while cold masses indicate that it will be chilly.
As they form at lower latitudes, tropical and equatorial air masses are hot. Those that form over land (continental) are drier and hotter than those that form over water, and they migrate poleward along the subtropical ridge's western perimeter. Trade air masses are a term used to describe tropical air masses that are found along the coast. The Caribbean Sea, the southern Gulf of Mexico, and the tropical Atlantic east of Florida, through the Bahamas, produce tropical air masses that impact the United States. The air masses that make up the monsoon are wet and unstable. Superior air masses are dry and only reach the earth on rare occasions.
They are most commonly seen over maritime tropical air masses, where they produce a warmer and drier layer above the more mild wet air mass below, resulting in a trade wind inversion.
Hence humidity and temperature is the correct option.

Note:
The main source of meteorological phenomena is a weather front, which is a barrier separating two masses of air of differing densities. Fronts are shown in surface weather studies using a variety of coloured lines and symbols, depending on the type of front. The temperature and humidity of the air masses separated by a front are generally different. Squall lines or dry lines may precede cold fronts, which can bring narrow bands of thunderstorms and severe weather.
