Meteorologists measure a variety of weather variables to prepare forecasts, including temperature, humidity, atmospheric pressure, wind speed and direction, and precipitation levels. They also analyze radar and satellite imagery to assess cloud cover and storm systems. Additionally, they consider historical weather data and patterns to improve the accuracy of their predictions. This comprehensive data collection helps them understand current conditions and project future weather scenarios.
Meteorologists use various instruments to predict rain, including weather radar to detect precipitation, satellites to monitor cloud formation, and weather balloons to measure atmospheric conditions. Additionally, weather models that simulate the atmosphere's behavior are also used in conjunction with these instruments to forecast rain.
Henrietta Leavitt was famous for her discovery of the relationship between the luminosity and the period of Cepheid variable stars. This discovery allowed astronomers to measure the distance to faraway galaxies and greatly contributed to our understanding of the universe's size and structure.
H II regions are regions of ionized gas in a galaxy that emit strong emission lines, allowing astronomers to determine the galaxy's distance using spectroscopy. Cepheid variables are pulsating stars with a period-luminosity relationship that allows astronomers to determine distances to galaxies based on their observed brightness variations. While both methods are used to measure extragalactic distances, they rely on different physical properties of objects within the galaxy.
A barometer is used to measure atmospheric pressure. It can also measure altitude!
A cloth tape measure.
Air pressure, temperature, wind direction and speed, and also where high and low pressures sit. They also have to know where all the warm, cold, stationary, and occluded fronts are. they both have the air pressure that crashes and makes a hurricane
dependent variables
yes
to measure forecast accuracy.
the only variables in an experiment are the independent variables [the thing in an experiment your going to change. and the dependent variables [the thing in an experiment your going to measure.

Scientists change the independent variable but measure the dependent variable; other variables are kept constant.
