... ο Air masses are at least around 1000 miles in horizontal extent. ο The temperature and moisture content of an air mass are not exactly uniform, but the horizontal gradients of these variables are small. The region where an air mass is formed is called the source region. ο In order to form, and ai ...

heated bar method
... The apparatus consists of a sample with rectangular cross-section clamped on one end by means of two aluminum blocks. Four flexible heaters are attached to the aluminum blocks that supply heat to the base of the sample. Heat is transferred by the sample via two pathways: 1. conduction through the so ...

Sky Watch: Weather
... By knowing how strong and in what direction the wind moves, we can often classify the type of wind as a breeze, a gale, a storm, tornado, or a hurricane. Go on a windy day adventure! Can you feel the push of the wind pulling you in a particular direction? Wind can be very powerful and can work to ma ...

Activity 2A: SURFACE WEATHER MAPS
... 2. The thick curved lines on the map are air mass boundaries. In the atmosphere, broad expanses of air with generally uniform temperature, humidity, and density come in contact with other masses of air having different temperature, humidity, and density. Because air masses of different densities do ...

Pressure and Density and the Temperature
... - Gravity causes the atmosphere to exert a downward force on the surface. - Simply put, it’s the weight of air above you. - Pressure falls off rapidly w/ height, so it doesn’t take long until air is very thin. - E.g. What’s the pressure in Lake Tahoe and Death Valley?? Look at a place’s elevation. - ...

Atmospheric convection

Atmospheric convection is the result of a parcel-environment instability, or temperature difference, layer in the atmosphere. Different lapse rates within dry and moist air lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threats from thunderstorms include hail, downbursts, and tornadoes.
