Modern astronomers define the tropical year as time for the Sun's mean longitude to increase by 360°. The process for finding an expression for the length of the tropical year is to first find an expression for the Sun's mean longitude (with respect to ♈︎), such as Newcomb's expression given above, or Laskar's expression.

The wet season, rainy season or green season is the time of year, ranging from one or more months when most of the average annual rainfall in a region falls. [9] Areas with wet seasons are disseminated across portions of the tropics and subtropics , some even in temperate regions. [ 10 ]
First, he proposed a correction to the length of the year. The mean tropical year is 365.24219 days long. [19] A commonly used value in Lilius's time, from the Alfonsine tables, is 365.2425463 days. [13] As the average length of a Julian year is 365.25 days, the Julian year is almost 11 minutes longer than the mean tropical year.
The Julian calendar ended up being 11 minutes and 14 seconds longer than the tropical year — the time it takes for seasons to repeat. In the late 16th century, Pope Gregory XIII improved the ...
From May 20-25, conditions may become favorable to support tropical formation, AccuWeather Lead Long-Range Meteorologist Paul Pastelok said, noting that one or two disturbances could travel across ...
The first time in 2001 led to the addition of tropical cyclone tracks for the years 1851 to 1885. The second time was in October 2002 when Hurricane Andrew (August 1992) was upgraded to a Category 5. Recent efforts into uncovering undocumented historical hurricanes in the late 19th and 20th centuries by various researchers have greatly ...
The Gulf of Mexico remains the zone to watch for tropical development and impacts to the United States in the days ahead, and this time Florida may be the prime target for any budding system next ...
Tropical climate is the first of the five major climate groups in the Köppen climate classification identified with the letter A.Tropical climates are defined by a monthly average temperature of 18 °C (64 °F) or higher in the coolest month, featuring hot temperatures and high humidity all year-round.
