2. Heating degree day - Wikipedia

   en.wikipedia.org/wiki/Heating_degree_day

   Heating degree day (HDD) is a measurement designed to quantify the demand for energy needed to heat a building. HDD is derived from measurements of outside air temperature . The estimated average heating energy requirements for a given building at a specific location are considered to be directly proportional to the number of HDD at that location.

3. Degree day - Wikipedia

   en.wikipedia.org/wiki/Degree_day

   Degree days are a useful metric for estimating energy consumption required for household heating and cooling, and in this context are formally referred to as heating degree days. Since the escape or ingress of heat due to conduction is proportional to the difference between the indoor and outdoor temperature, the amount of energy needed to ...

4. Growing degree-day - Wikipedia

   en.wikipedia.org/wiki/Growing_degree-day

   Growing degree days (GDD), also called growing degree units (GDUs), are a heuristic tool in phenology.GDD are a measure of heat accumulation used by horticulturists, gardeners, and farmers to predict plant and animal development rates such as the date that a flower will bloom, an insect will emerge from dormancy, or a crop will reach maturity.

5. Temperature - Wikipedia

   en.wikipedia.org/wiki/Temperature

   Temperature is a physical quantity that quantitatively expresses the attribute of hotness or coldness. Temperature is measured with a thermometer.It reflects the average kinetic energy of the vibrating and colliding atoms making up a substance.

6. Heat wave - Wikipedia

   en.wikipedia.org/wiki/Heat_wave

   A heat wave or heatwave, sometimes described as extreme heat, is a period of abnormally hot weather. [1]: 2911 A time period of five consecutive days is often used to define a heat wave but the exact definition of a heat waves can vary for

8. Thermal physics - Wikipedia

   en.wikipedia.org/wiki/Thermal_physics

   Thermal physics, generally speaking, is the study of the statistical nature of physical systems from an energetic perspective. Starting with the basics of heat and temperature, thermal physics analyzes the first law of thermodynamics and second law of thermodynamics from the statistical perspective, in terms of the number of microstates corresponding to a given macrostate.

9. Here's A Big Bird's Eye-View Of The Brand New Sesame Street

   "Sesame Street" has been gentrified. After 45 seasons, the brick walls that once fenced in the neighborhood have been razed, giving way to sweeping views of what looks suspiciously like the Brooklyn Bridge (it is in fact a composite of three New York City bridges).
