Rain gauge. A rain gauge (also known as udometer, pluviometer, ombrometer, and hyetometer) is an instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation over a predefined area, over a period of time. [1] It is used to determine the depth of precipitation (usually in mm) that occurs over a unit ...
Spacecraft. The Tropical Rainfall Measuring Mission (TRMM), one of the spacecraft in the NASA Earth Probe series of research satellites, is a highly focused, limited-objective program aimed at measuring monthly and seasonal rainfall over the global tropics and subtropics. TRMM is a joint project between the United States and Japan to measure ...
Probability theory. In probability theory and statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable. The general form of its probability density function is. The parameter is the mean or expectation of the distribution (and also its median and mode ), while ...
Hilo /ˈhiːloʊ/ (Hawaiian pronunciation: [ˈhilo]) is the largest settlement in Hawaii County, Hawaii, United States,[1] which encompasses the Island of Hawaii, and is a census-designated place (CDP). The population was 44,186 according to the 2020 census.[2] It is the fourth-largest settlement in the state of Hawaii and largest settlement ...
Example of samples from two populations with the same mean but different variances. The red population has mean 100 and variance 100 (SD=10) while the blue population has mean 100 and variance 2500 (SD=50) where SD stands for Standard Deviation. In probability theory and statistics, variance is the expected value of the squared deviation from the mean of a random variable.
2014 Southeast Europe floods. Between 13 and 18 May 2014 a low-pressure cyclone [9] designated Tamara and Yvette affected a large area of Southeastern and Central Europe, causing floods and landslides. Serbia and Bosnia and Herzegovina suffered the greatest damage, as the rain was the heaviest in 120 years of recorded weather measurements.
The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. It was formed 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc.The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its outer photosphere.
