The EFFECT OF LAND WIDTH ON LAND-SEA BREEZE
By Using WRF.4.0.3 & NCL
FLORIDA
"Although the differential heat capacity of land and ocean is the fundamental driving force of land and sea breeze, other geophysical variables like latitude dependence (e.g., Rotunno 1983), ambient wind (e.g., Qian et al. 2009), shoreline curvature (e.g., Baker et al. 2001), inland terrain (e.g., Qian 2012), atmospheric stability (e.g., Walsh 1974), land cover (e.g., Zhang et al. 2005), land use (e.g., G. Chen et al. 2015), and the urban heat island circulation (e.g., Freitas et al. 2007) can also dramatically influence the characteristics of the land and sea breeze."
"In consequence, the land- and sea-breeze circulations often vary markedly from region to region."
So, it makes difference between the ideal cases that we made and the real case.
Florida is the southernmost contiguous state in the united states. The state is bordered to the west by the Gulf of Mexico, to the northwest by Alabama, to the north by Georgia, to the east by the Atlantic Ocean, and to the south by the Straits of Florida.

Since it is a peninsula bordering on the ocean in the east and west, and thunderstorms are caused by the collision of the sea breeze.
Florida Sea Breeze Collision
Florida is about 582 kilometers wide. So it's not appropriate for the sea breeze to collide. However, the width of the place that sea breeze collision occur, which appeared in the previous video, is about 170 kilometers. Also, Florida's highest point is only 105 meters in britton hill. Therefore, it is possible to have a sea breeze collision.
UF Weather - Classic Sea Breeze Collision Recap
The following is an excerpt from a paper analyzing the cause of Florida’s thunderstorms.
Low-level horizontal convergence caused by the afternoon sea breezes entering the peninsula from both sides was found to be the most rational explanation of the thunderstorms.
Using the Bellamy “triangle method” applied to pilot-balloon stations it was found that low-level convergence developed practically every afternoon during the summer months as a result of this diurnal sea-to-land circulation.
The effects extended to an altitude of 3000 or 4000 ft. A comparison with adjacent regions showel that the double sea-breeze effect of the peninsula produces much greater and more consistent convergence than that found along the northern Gulf Coast, thus accounting for the very striking maximum frequency of thunderstorms in the interior of the peninsula.
