Scientists have used tree-ring data and sediment cores from lakebeds to study past climate conditions. By analyzing these data, researchers have been able to determine that there was a severe drought in the Jamestown area during the time of its settlement, which likely contributed to the difficulties faced by the colonists.

Instruments such as a sextant or a quadrant can be used to determine the altitude of the North Star. By measuring the angle between the North Star and the horizon, navigators can determine their latitude.

Measurements of the distance between rings in the trunks of trees near Jamestown determined that there may have been a drought during the time Jamestown was settled.

The most commonly used scale to measure drought is the Palmer Drought Severity Index (PDSI). It takes into account factors such as temperature, precipitation, and soil moisture to determine drought severity. The scale ranges from -10 (extremely dry) to +10 (extremely wet), with zero indicating normal conditions.
Lilly, who is a scientist, used a seismograph to determine the strength of the earthquake that had just hit Haiti.
A period with little rain is a drought.(The archaic equivalent was drouth.)
