atpl/oxford/met/ch5 Flashcards
The measurement of surface temperature is made:
at approximately 4 feet above ground level
The purpose of a “Stevenson Screen” is to:
protect the thermometer from wind, weather and from direct sunshine
If temperature remains constant with an increase in altitude there is:
an isothermal layer
The surface of the earth is heated by:
short wave solar radiation
Cloud cover will reduce diurnal variation of temperature because:
incoming solar radiation is reflected back to space and outgoing terrestrial radiation is re-radiated from the cloud layer back to the surface
Diurnal variation of the surface temperature will:
decrease as wind speed increases
Which of the following surfaces is likely to produce a higher than average diurnal variation of temperature:
rock or concrete
Most accurate temperatures above ground level are obtained by:
radio sonde
The method by which energy is transferred from one body to another by contact is called:
conduction
The diurnal variation of temperature is:
reduced anywhere by the presence of cloud
The troposphere is heated largely by:
conduction from the surface, convection and the release of latent heat
An inversion is one in which:
there is an increase of temperature as height increases
The sun gives out________ amount of energy with _________ wavelengths.
The earth gives out relatively___________ amounts of energy with relatively___________ wavelengths:
Large, small, small, large.
With a clear night sky, the temperature change with height by early morning is most likely to show:
An inversion from near the surface and a 2°C per 1000 ft lapse rate above.
Over continents and oceans, the relative temperature conditions are:
Colder in winter over land, warmer in winter over sea.
