Mid-Latitude Cyclones. Geostrophic Winds. Geostrophic Wind. Wind flowing in a straight path, parallel to the isobars at a constant speed.. Above the influence of friction (the Boundary Layer) a given parcel will accelerate toward the lower pressure due to the PGF.. de-patterning) circulations, such patterning should also enhance the food web. Fronts and intensify vertical laterally convergent gences. These produce alternating upwelling flow. eddy denotes an area Front: a boundary between 2 air masses. Warm air and cold air do not mix well.. Changes in weather occur along fronts.. 4 Types of fronts:. Cold Front. Warm front. Stationary front. Occluded front. 1. Cold Front. “Whirlwind Theory”. Rotation. Coriolis. Espy. Convergence into Low. PGF. 1841. Loomis. Rotation AND Convergence. 1860. Early Maritime Observations (Winds). http://m.nautil.us/issue/25/water/the-dueling-weathermen-of-the-1800s. Lab. Fronts!. Fronts!. What are fronts?. A narrow transition zone, or boundary, between differing synoptic scale air masses whose primary discontinuity is density. Fronts highlight . baroclinic. zones, where temperature advection and atmospheric energy is at work.

A front is defined as the transition zone between two air masses of different density. . & . the weather they bring. Have you ever wondered why we get certain kinds of weather…cloudy days with lots of rain…sudden storms, then cooler weather…?. All weather happens because of the 4 types of fronts & how they interact:. 3. Its structure, composition and dynamics. In last week’s lecture, we focussed on how weather is generated.. The key ingredients are energy and gradients.. Last Week’s Lecture. Incoming energy from the Sun is balanced with outgoing radiative cooling of the Earth, resulting in an equilibrium temperature of about 15 °C. . Weather Maps. Storms. Weather Maps. Weather Stations. Show the following data. in a concise way:. . - cloud cover. . - wind direction. . - wind speed. . - temperature. . - precipitation. . air masses.. . An . Air Mass. is an immense body of air, some 1600+ km (~1000mi) across and 1-3 km (~.6 to 1.9mi) thick, with relatively homogeneous physical properties (density, T. . and moisture) at a given altitude..
