daily mean temperature
This is usually the average of the highest and the lowest temperatures in a 24-hour period
daily temperature range
This is the difference between the highest and the lowest temperatures in a 24-hour period
monthly mean temperature
To determine this you must divide the total of the daily means of a month by the number of days in a month.
annual mean temperature
This is the average of 12 monthly mean temperatures for a location
annual temperature range
This is the difference between the warmest and coldest monthly mean temperatures for a location
isotherm
This is a line of equal temperature
temperature gradient
This is the change in temperature per unit of distance
differential heating of land and water, ocean currents, altitude, geographic position, and cloud cover and albedo
These are the five main controls of temperature
differential heating of land & water
This control of temperature relates to the fact that land heats more rapidly and to higher temperatures than water, and land cools more rapidly and to lower temperatures than water
water is highly mobile, land surfaces are opaque, the specific heat, and evaporation is greater from water than land
These aer the four main reasons for the differential heating of land and water
ocean currents
This control of temperature generally results from the drag caused by wind blowing accross the ocean surface
01-Apr
How much of the transfer of heat between the tropics and high latitude regions is due to ocean currents?
altitude
This control of temperature is related to the change in temperature one experiences as one rises through the troposphere
geographic position
Some examples of this control of temperature include windward vs. leeward locations, effects of intervening mountains, and latitude
cloud cover & albedo
This control of temperature relates mainly to the reflective (and insulating) characteristics of clouds
urban heat island
This phenomenon relates to the differential heating of urban areas relative to the surrounding country side
daytime
Is the heat island effect generally more pronounced in the daytime of the nighttime?
land
Is the annual range of temperature highest over land or over water?
Myanmar
What area of the world has the greatest range of temperatures?
near sunrise
In a 24-hour period, when does the lowest temperature usually occur?
temperature variations
Why does the highest temperature in a 24-hour period usually occur awhile after the peak of incoming solar radiation?
lag in temperature
Why does the highest temperature in a year usually occur weeks after the day when the greatest amount of solar radiation is received?
lag in temperature
Why does the lowest temperature in a year usually occur weeks after the day when the least amount of solar radiation is recieved?
mechanical thermometers
These thermometers include liquid-in-glass thermometers and bimetal strip thermometers
electrical thermometers
These thermometers include thermisters and infrared thermometers
fahrenheit
This tempearature scale (at 1 atmosphere) includes 212 degrees for boiling, 32 degrees for freezing, and -459.7 degrees for absolute zero
celsius
This temperature scale (at 1 atmosphere) includes 100 degrees for boiling, 0 degrees for freezing, and -273 degrees for absolute zero
kelvin
This temperature scale (at 1 atmosphere) includes 373 degrees for boiling, 273 degrees for freezing, and 0 degrees for absolute zero
heating degree days
This type of degree day is useful for determining the amount of insulation needed for buildings or the amount of energy needed for heating
cooling degree days
This type of degree dayis useful for determining the necessity for air conditioning
growing degree days
This type of degree day is useful for determining when to harvest crops
windchill
Wind can make a temperature feel much lower than it really is. A human body loses heat much more quickly the stronger the wind. What is this phenomenon called?
heat index
This is related to humidy. The more humid days feel warmer than drier days and can lead to more heat stress for people. What is this phenomenon called?
heat
Which weather related phenomenon is responsible for more deaths than any other?
