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.
Air masses build over source regions that have relatively similar ground surface characteristics. Air masses that build over the land are called continental air masses while air masses that build over the open ocean are called maritime air masses. Air masses cover 100 s to 1000 s of kilometers of distance. What causes these huge regions of air to move? Air masses build when the air stagnates over a region for several days/weeks. To move these huge regions of air, the weather pattern needs to change to allow the air mass to move. One major influence of air mass movement is the upper level winds such as the upper level winds associated with the jet stream.
