Some tools used by meteorologists: satellite products. Visible images are useless at night: infrared satellite )mage: you are (cid:498)seeing(cid:499) the temp of the cloud tops or of the earth"s surface. This sensor can be used night and day. Black= warm temperatures; cloud tops usually colder than surfaces and. 35,000 regularly reporting surface weather stations across the globe: these observations are critically important for weather forecasting, and understanding the, we do not do a good job at all of observing the atmosphere over the ocean. Surface observations earth"s climate: deos highest resolution state weather network in the u. s. Delaware environmental observing system: stations report weather every 5 minutes. The winds spiral clockwise around an area of high pressure: cold front: blue lines with teeth, warm front: red lines with half circles, high low pressure systems move from the west to the east. Circle gives station location (half of the sky because half filled)
