question: Why is it more windy during the day than in the morning?
comment: Winds are driven by differences in air pressure. If you live near large bodies of water, the air over the water heats up at a different rate than the air over the land, resulting in differences in temperature and pressure. Early in the morning, the temperature/pressures are similar, thus no wind. Google “sea breeze” and “land breeze” for a more thorough explanation. If you want some impressive stuff, look at Florida where you have two opposing sea breezes that collide in the middle of the state and crank up some impressive thunderstorms.
passages: During the afternoon, air pressure decreases over the land as the warmer air rises. The relatively cooler air over the sea rushes in to replace it. The result is a relatively cool onshore wind. This process usually reverses at night where the water temperature is higher relative to the landmass, leading to an offshore land breeze. However, if water temperatures are colder than the land at night, the sea breeze may continue, only somewhat abated. This is typically the case along the California coast, for example.
   A 2010 study found that in the immediate vicinity of wind farms, the climate is cooler during the day and slightly warmer during the night than the surrounding areas due to the turbulence generated by the blades.
   In addition to these winds, there is daily pattern of land breezes in the morning, followed by the onset of south-westerly sea breezes in the afternoon. This pattern is caused by temperature differences between the land and the ocean, and is not as strong in the Houtman Abrolhos as on the mainland, but is present nonetheless.
   Parker (2006) found that there was no difference in warming between calm and windy nights. Since the urban heat island effect is strongest for calm nights and is weak or absent on windy nights, this was taken as evidence that global temperature trends are not significantly contaminated by urban effects. Pielke and Matsui published a paper disagreeing with Parker's conclusions.
   BULLET::::- Inversions. When on a clear and calm night, a radiation inversion is formed near the ground, the friction does not affect wind above the top of the inversion layer. The change in wind can be 90 degrees in direction and in speed. Even a nocturnal (overnight) low level jet can sometimes be observed. It tends to be strongest towards sunrise. Density differences cause additional problems to aviation.
   The daily (diurnal) longitudinal effects are at the mesoscale (a horizontal range of 5 to several hundred kilometres). During the day, air warmed by the relatively hotter land rises, and as it does so it draws a cool breeze from the sea that replaces the risen air. At night, the relatively warmer water and cooler land reverses the process, and a breeze from the land, of air cooled by the land, is carried offshore by night.

   Studies in 2004 and 2006 attempted to test the urban heat island theory, by comparing temperature readings taken on calm nights with those taken on windy nights. If the urban heat island theory is correct then instruments should have recorded a bigger temperature rise for calm nights than for windy ones, because wind blows excess heat away from cities and away from the measuring instruments. There was no difference between the calm and windy nights, and one study said that "we show that, globally, temperatures over land have risen as much on windy nights as on calm nights, indicating that the observed overall warming is not a consequence of urban development."
   There are occasions where a storm system might rain itself out before reaching the observer (who had seen the morning red sky). For ships at sea however, the wind and rough seas from an approaching storm system could still be a problem, even without rainfall.
  
  Because of different prevailing wind patterns around the globe, the traditional rhyme is generally not correct at lower latitudes of both hemispheres, where prevailing winds are from east to west. The rhyme is generally correct at mid-latitudes where, due to the rotation of the Earth, prevailing winds travel west to east.

   Wind speeds are often lower in cities than the countryside because the buildings act as barriers (wind breaks). On the other hand, long streets with tall buildings can act as wind tunnels – winds funnelled down the street – and can be gusty as winds are channelled round buildings (eddying).

   Chicago is not significantly windier than any other U.S. city. For example, the average annual wind speed of Chicago is ; Boston: ; Central Park, New York City: ; and Los Angeles: .
  
  The following "windy city" explanation is from the "Freeborn County Standard" of Albert Lea, Minnesota, on November 20, 1892:
  
  An explanation for Chicago being a naturally breezy area is that it is on the shores of Lake Michigan.

  The winds on a typical day in Savannah begin is as follows:
  
  BULLET::::- In the morning a light breeze from the west to the Northwest at about 5 knots
  
  BULLET::::- The winds diminish in the late mornings
  
  BULLET::::- By midday, the sea breeze circulation begins. When the sea breeze does rise, the winds backs to the south and Southeast
  
  BULLET::::- Wind speed in the afternoon average between 7 and 12 knots
   At night, the land cools off more quickly than the ocean because of differences in their specific heat values. This temperature change causes the daytime sea breeze to dissipate. When the temperature onshore cools below the temperature offshore, the pressure over the water will be lower than that of the land, establishing a land breeze, as long as an onshore wind is not strong enough to oppose it.

   An analysis of ground weather from 1993 to 2001 at the automatic weather station at Homigot's northern tip showed a distinct difference between summer and winter of wind speed. Starting in October, the wind speed slowly increased, reaching its peak in December and January, and gradually decreasing until July. The average wind speed of more than 5 m/s was measured from December to March, but the average wind speed was below 4 m/s from May to August. In other words, wind speeds tend to remain strong at night in winter and fall during daytime. On the other hand, the wind speed increases in the spring and summer between 3-4 p.m., and the wind speed is maintained almost constant in autumn. Therefore, it is considered that the energy generated by wind power will be concentrated in the winter night time.

   Chicago is known as the Windy City. The "Windy City" moniker did not originally refer to Chicago's climate. It is believed to have been created by a New York newspaper writer deriding Chicagoans' bluster as they promoted their city as the site of the 1893 Columbian Exposition. In terms of climate, Chicago is slightly windier than the average American city. Average wind speeds range from in late summer to in spring months.

   If the Santa Anas are strong, the usual day-time sea breeze may not arise, or develop weak later in the day because the strong offshore desert winds oppose the on-shore sea breeze. At night, the Santa Ana Winds merge with the land breeze blowing from land to sea and strengthen because the inland desert cools more than the ocean due to differences in the heat capacity and because there is no competing sea breeze.
  
  Section::::Description.:Regional impacts.
   The strength of the sea breeze is directly proportional to the temperature difference between the land mass and the sea. If an off-shore wind of exists, the sea breeze is not likely to develop. At night, the land cools off more quickly than the ocean due to differences in their specific heat values, which forces the daytime sea breeze to dissipate. If the temperature onshore cools below the temperature offshore, the pressure over the water will be lower than that of the land, establishing a land breeze, as long as an onshore wind is not strong enough to oppose it.
   From late September through early November, the area experiences an abrupt autumn during which normal temperatures drop very rapidly and cloudy, wet weather quickly picks up. Prior to the sudden onset of the rainy season in mid- to late fall, there are often days with a very wide disparity between daytime and nighttime temperatures, sometimes exceeding . There is far less wind in the fall than in spring and early summer, though passing frontal systems can still bring quick bouts of strong wind.
