Weather is always a mixed bag. Are you ready to handle it?

1. 1) What type of cloud is this, and what weather is associated with it?

2. 2) Which answer describes a low pressure system near the surface (northern hemisphere)?

   A low pressure system at the surface flows counter-clockwise and converges at the center of the low pressure system.

5. 5) You're at Seattle-Tacoma International airport (433' MSL) and it's a standard day (ISA). Approximately what altitude would you find a temperature of -1 degrees Celsius?

   The standard lapse rate is 2 degrees for every thousand feet. ISA standard temperature is 15 degrees. The difference between 15 and -1 is 16 degrees. Dividing this value by 2 (two degrees per thousand feet) will give 8. Multiply this value by 1,000 and you get an altitude of 8,000 ft.

6. 6) What type of icing did this aircraft accumulate?

   Mixed ice is a cloudy combination of clear and rime ice. It's often found in stratiform clouds, with the most intense icing near the top of the cloud.
