<li><span style="font-size: large;">The type of front depends on both the direction in which the air mass is moving and the characteristics of the air mass. </span><span style="color: #00007f; font-size: large;">There are four types of fronts: cold front, warm front, stationary front, and occluded front.</span></li>

<li><span style="font-size: large;">changes in the moisture content of the air (dew point), </span></li>
<li><span style="font-size: large;">shifts in wind direction, </span></li>
<li><span style="font-size: large;">low pressure troughs and pressure changes, and </span></li>
<li><span style="font-size: large;">clouds and precipitation patterns. </span></li>
</ul><span style="color: #00007f; font-size: large;">(Not all of these patterns may be obvious or even occur, but these are some signs.)</span></li>

</ul><span style="color: #674ea7;">How are cold weather fronts formed?</span><br />
<span style="color: black;">Forms when a cold air mass pushes under a warm air mass, forcing the warm air to rise.</span><br />
<span style="color: #674ea7;">What weather a cold front will bring?</span><br />
Thunderheads can form as the moisture in the warm air mass rises, cools, and condenses. As the front moves through, cool, fair weather is likely to follow.<br />
<br />
<ul><li><span style="color: #3d85c6; font-size: large;">Warm Weather Front!</span></li>
</ul><span style="color: #674ea7;">How are warm weather fronts formed?</span><br />
Forms when a moist, warm air mass slides up and over a cold air mass.<br />
<span style="color: #674ea7;">What weater will a warm front bring?</span><br />
As the warm air mass rises, it condenses into a broad area of clouds. A warm front brings gentle rain or light snow, followed by warmer, milder weather.<br />
<br />
<ul><li><span style="color: #3d85c6; font-size: large;">Stationary Weather Front!</span></li>
</ul><span style="color: #674ea7;">How are stationary weather fronts formed?</span><br />
Forms when warm and cold air meet and neither air mass has the force to move the other. They remain stationary, or “standing still.”<br />
<span style="color: #674ea7;">What weather will a stationary front bring?</span><br />
Where the warm and cold air meet, clouds and fog form, and it may rain or snow. Can bring many days of clouds and precipitation.<br />
<br />
<ul><li><span style="color: #3d85c6; font-size: large;">Occluded Weather Front!</span></li>
</ul><span style="color: #674ea7;">How are Occluded fronts formed?</span><br />
Forms when a warm air mass gets caught between two cold air masses. The warm air mass rises as the cool air masses push and meet in the middle.<br />
<span style="color: #674ea7;">What weather will a occluded front bring?</span><br />
The temperature drops as the warm air mass is occluded, or “cut off,” from the ground and pushed upward. Can bring strong winds and heavy precipitation.giggles45http://www.blogger.com/profile/15402817976817001500noreply@blogger.com0tag:blogger.com,1999:blog-6933654281794327928.post-42441224959776883482011-05-25T12:16:00.000-07:002011-05-25T12:16:10.301-07:00Warm &Cold weather fronts!<div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/-0hYTDAvoGc4/Td1VXyOyz_I/AAAAAAAAAAc/6TwaSR0N0rE/s1600/3_warmcoldfronts.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://2.bp.blogspot.com/-0hYTDAvoGc4/Td1VXyOyz_I/AAAAAAAAAAc/6TwaSR0N0rE/s320/3_warmcoldfronts.jpg" t8="true" width="308" /></a></div><span style="background-color: black;"></span>giggles45http://www.blogger.com/profile/15402817976817001500noreply@blogger.com0tag:blogger.com,1999:blog-6933654281794327928.post-29050294710386773312011-05-24T12:23:00.000-07:002011-05-25T11:58:59.464-07:00Cold Weather Fronts<ul><li><span style="color: magenta; font-family: "Helvetica Neue", Arial, Helvetica, sans-serif; font-size: large;"><u>What are cold weather fronts?</u></span></li>
</ul><span style="color: magenta; font-family: "Helvetica Neue", Arial, Helvetica, sans-serif; font-size: large;">Well, a cold weather front is decribed as the changeover in an area. Where the cold air is replaced with the warm air.</span><br />
<ul><li><span style="color: magenta; font-family: Arial; font-size: large;"><u>Why does the cold air replace the warm air?</u></span></li>
</ul><span style="color: magenta; font-family: Arial; font-size: large;">Because, the cold air pushes the warm air upward.</span><br />
<br />
<ul><li><span style="color: magenta; font-family: Arial; font-size: large;"><u>What direction do cold fronts travel?</u></span></li>
</ul><span style="color: magenta; font-family: Arial; font-size: large;">Cold weather fronts move Northwest to Southeast.</span><br />
<br />
<ul><li><span style="color: magenta; font-family: Arial; font-size: large;"><u>What is it like after a cold front?</u></span></li>
</ul><span style="color: magenta; font-family: Arial; font-size: large;">The air that comes after cold front is cooler than the air before the frony. The cold front can make the temperature drop 15 degrees in an hour. Also the cold fronts move faster than warm fronts.</span>giggles45http://www.blogger.com/profile/15402817976817001500noreply@blogger.com0tag:blogger.com,1999:blog-6933654281794327928.post-7441182714786864032011-05-20T12:22:00.000-07:002011-05-25T12:16:49.654-07:00Weather Fronts!<div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-v4kZflk4OBQ/Tda_MNDM9VI/AAAAAAAAAAY/faaum2SwNKQ/s1600/Fronts.gif" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://1.bp.blogspot.com/-v4kZflk4OBQ/Tda_MNDM9VI/AAAAAAAAAAY/faaum2SwNKQ/s320/Fronts.gif" width="320" /></a></div>giggles45http://www.blogger.com/profile/15402817976817001500noreply@blogger.com1
