TRUE/FALSE questions for metreology
1) You read a weather report that states that for a specific date, the normal (norm) high temperature is 70deg F. In this case, the 70deg norm represents the average of all high temperatures for that date taken over a 30 year period.
2) Temperature drops at a rate (-deg/elev) known as the Adiabatic Lapse Rate. If it is 'dry' (not saturated), it will rise and expand experiencing temperature drop as heat energy is absorbed during the expansion process. If, on the other hand, it is saturated, then it will rise, expand and reach its dew point temperature causing the water vapor in it to condense on condensation nuclei.
3) You read a weather report that states that for a specific date, the normal (norm) high temperature is 70deg F. In this case, the 70deg norm represents the average of all high temperatures for that date taken over a 30 year period.
4) An anemometer displays wind direction, wind speed, and type of precipitation.
5) Gaps or passes in mountain ridges can increase the flow (speed) of wind.
6) When viewing an infrared satellite image of clouds (black & white image), white areas have little water vapor (dry air), while dark areas represent moist weather systems.
7) Other conditions being equal, a city at low latitude would probably have a higher mean annual average temperature and a lower annual range of temperature than a city at high latitude.
8) “Heat lightening” are bolts of lightning that can occur from clear skies (i.e., no clouds) and are caused by the atmosphere being very warm relative to the ground.
Explanation / Answer
1) The statement is FALSE. This is because, if the data is taken as an average value of data record of over 30 years, then it is about climate report, not weather. Weather and climate have a different sense of meaning.
2) The statement is TRUE. This is because, when a rising air parcel has little moisture, condensation during upliftment is low, the latent heat of condensation released is low. As a result, decrease in temperature is higher. Similarly, when an air parcel that is saturated (stomach full) with water vapour rises, some of the vapour will condense and release latent heat.
3) The statement is FALSE. This is because, if the data is taken as an average value of data record of over 30 years, then it is about climate report, not weather. Weather and climate have a different sense of meaning.
4) The statement is FALSE. This is because, anemometer does display wind speed and wind direction but does not display type of precipitation.
5) The statement is TRUE. This is because, as the air passes through the gap the air is squeezed into a tighter passage which increases the speed of the wind.
6) The statement is FALSE. This is because, white and brighter areas of clouds indicate colder and thick clouds, filled with moisture and darker areas represent thin clouds.
7) The statement is TRUE. This is because, as we go northward or southward from equator, temperature decreases with latitude. So, other conditions kept equal, a city at lower latitude would probably have a higher temperature than one at higher latitude.
8) The statement is TRUE. This is because, heat lightning occurs even if there is no rain. It is silent lightning, and is result of a certain thunderstorm occuring at a greater distance from the site of its occurence. It mostly occur in hot and humid days.
