The highest reliably recorded temperature in the world, [6] [7] 134 °F (56.7 °C), was recorded in Death Valley on July 10, 1913. Temperatures of 130 °F (54 °C) or higher have been recorded as recently as 2005. The 24-hour average July temperature in Death Valley is 101.8 °F (38.8 °C) (1981–2010 NCDC Normals).
The warmest month has an average temperature of below 22 °C (72 °F). Tierra fría (Cool land) below 3,600 m (11,800 ft). The warmest month has an average temperature of below 18 °C (64 °F). Tierra helada (Cold land) above 3,600 m (11,800 ft). The tree line occurs when the warmest month has an average temperature of below 10 °C (50 °F).
Thus the standard consists of a tabulation of values at various altitudes, plus some formulas by which those values were derived. To accommodate the lowest points on Earth, the model starts at a base geopotential altitude of 610 meters (2,000 ft) below sea level, with standard temperature set at 19 °C.
The NASA Earth Global Reference Atmospheric Model (Earth-GRAM) was developed by the Marshall Space Flight Center to provide a design reference atmosphere that, unlike the standard atmospheres, allows for geographical variability, a wide range of altitudes (surface to orbital altitudes), and different months and times of day. It can also ...
Map of California topography and geomorphic provinces California's major mountain ranges. California is a U.S. state on the western coast of North America. Covering an area of 163,696 sq mi (423,970 km 2), California is among the most geographically diverse states.
The topographic elevation of a summit measures the height of the summit above a geodetic sea level. [b] [c] The first table below ranks the 50 highest major summits of California by elevation. The topographic prominence of a summit is a measure of how high the summit rises above its surroundings.
The greater the altitude, the lower the pressure. When a barometer is supplied with a nonlinear calibration so as to indicate altitude, the instrument is a type of altimeter called a pressure altimeter or barometric altimeter. A pressure altimeter is the altimeter found in most aircraft, and skydivers use wrist-mounted versions for similar ...
Essentially, the mountain ranges separate southern California into two distinct climatic regions: The heavy-populated coastal area west of these mountains is the one most associated with the term "southern California" and is characterized by pleasant weather all-year round, without frequent heat spells in the summer and without low temperatures ...
