Q.1
Summer storms are harder to forecast than winter storms because
*
forecasters concentrate on winter storms as they are more destructive.
winter storms must break through a "cap" in the atmosphere before they can gain strength.
Summer convective systems can "slip between the cracks" because they are small and only last a few hours.
Snow is easier to see on radar than rain.
Q.2
Doppler radar has untapped potential to aid forecasters because it
*
can directly detect temperature and humidity.
needs to be expanded to scan the entire United States.
has a longer range than conventional radar.
produces data that can be analyzed in the context of surrounding atmospheric conditions.
Q.3
True or false: Geostationary satellites have a natural advantage for detecting conditions at different levels of the atmosphere:
*
True
False
Q.4
One way forecasters check the accuracy of their forecasts is by
*
adding new data and rerunning their forecast models.
looking at historic predictions for the same day in other years.
running the forecast calculations manually instead of in a computer.
They don’t check: Forecasters are concerned with the future, not the past.
Q.5
One reason to doubt that methane releases will cause global warming feedback comes from
*
ice cores, which show that methane levels rose following warmings in the past.
low levels of methane in the atmosphere near the North Pole.
studies showing that methane is much weaker than carbon dioxide as a greenhouse gas.
the inability to find methane in the atmosphere above the ocean.
