Use Intellicast.com to answer the following: • What type of front is moving into NC? • How will this front affect our weather? • What is our air pressure over NC (see little number on map) Do Now
McDougall, p.A84 High- and Low-Pressure Systems In your notebook, write what you observe about the differences between H (high pressure) and L (low pressure) based on the two images below:
High pressure system Air moves down, out, and clockwise Low pressure system Air moves in, up, and counterclockwise http://www.bom.gov.au/lam/Students_Teachers/pressure.shtml High- and Low-Pressure Systems
McDougall, p.A101 Isobars Isobars are lines that connect areas with the same air pressure. They are used to identify areas of high and low pressure. They also help forecast wind speed and direction. Below air pressure is measured in millibars (mBars).
