Packaging Your Fragrances Properly. When shipping perfume bottles with the USPS, you need to take the time and care to prepare your shipments correctly to ensure they arrive in the hands of your customers in one piece. Perfume bottles are fragile and can be shattered in transit, if not packed carefully.
What is an air mass? An airmass is a large (usually thousands of miles across) volume of air that has horizontally uniform properties in terms of temperature, and to a lesser extent humidity. Airmasses acquire their properties from spending days to weeks over the same part of the Earth: say over northern Canada, the North Pole, the tropical Pacific Ocean, etc.
two of these air masses: the cold, dry air mass coming from Canada, and the warm, moist. air mass that forms over the Gulf. The cold, dry Candian air mass is an example of a cP. air mass, standing for continental (dry) polar (cold). The warm, moist air that forms over. the Gulf and generates almost all of the precipitation over the Eastern 2/3 of the United. States is an example of an mT air mass, meaning maritime (moist) Tropical (warm).
