Not all flowers bloom in spring. Those that do so largely because they need to set fruit or seed and have it mature before winter.
In the winter, the fruits would not be able to withstand the cold and freeze. Sometimes, the flower's petals will wither during and die in the winter, so they must bloom during the spring, the season of warmth and new life.

Red tides are a natural phenomenon caused by an increase in the amount of nutrients that algae need usually due to farm runoff. When the amount of nutrients reaches a certain level there is a significant increase in Karenia Brevis algae. Many also believe that red tides occur when there is a combination of very high temperatures, wind, and rainfall.Red tides is mostly caused by the increase of temperature and the difference of temperature between hot surface and a cold layer beneath the hot surface. When it is night, the dinoflagellates move to the cold layer to absorb nutrients. When it is day, they move to top to photosynthesize.Red tides are caused by algal blooms. Certain types of algae in the ocean multiply at rapid rates, typically by excess nutrients found in the water. The algae die and the decay process consumes the oxygen in the water -- one of the reasons these red tides are so destructive.By the way, not all algal blooms are red. It all depends on the algae present which grow quickly.A bloom of red algae, usually due to increased nutrients in the water.These extra nutrients can come either from natural sources or human caused pollution.The red algae both deplete oxygen in the water and produce toxins, which kill fish and other sealife. The toxins can also kill people if they eat seafood (especially filter feeders e.g. clams, mussels, oysters, scallops) caught during the period of the red tide or immediately afterwards.
Tornadoes usually occur in spring and early summer while hurricanes usually occur in summer and early fall. However, tornadoes can occur at any time of year, and out of season hurricanes have occurred as well.
diffusion is occur when different concentration gradient is applied
Worldwide, typhoon activity peaks in late summer, when the difference between temperatures aloft and sea surface temperatures is the greatest. However, each particular basin has its own seasonal patterns. On a worldwide scale, May is the least active month, while September is the most active
An algal bloom is a rapid increase or accumulation in the population of algae (typically microscopic) in an aquatic system. Algal blooms may occur in freshwater also.
Clusters of algae are called algal blooms. These blooms can occur when conditions are favorable for algae growth, such as high nutrient levels and warm temperatures. While some algal blooms are harmless, others can produce toxins that can be harmful to aquatic life and humans.

The most recent red tide event occurred in Florida in 2021, impacting the Gulf of Mexico and causing environmental and economic concerns due to the harmful algal blooms.
Algae blooms are a form of bacteria and can cause skin irritation or respiratory irritation in people who get in the water or handle the algae. Some blooms of blue-green algae can produce chemicals that are toxic to animals and people who drink the untreated water.
it mostly occurs in the spring time
After a lake receives a large input of a limiting nutrient such as phosphorus or nitrogen, excessive algal growth can occur. This can lead to algal blooms which deplete oxygen levels in the water, harm aquatic life, and disrupt the ecosystem balance. Additionally, the increased algal growth can lead to a phenomenon known as eutrophication, where the lake becomes overly enriched with nutrients and can become turbid and inhospitable to many organisms.
Red tides, which are caused by algal blooms, most commonly occur in coastal areas with nutrient-rich waters, such as along the coast of Florida in the Gulf of Mexico. They can also occur in other regions worldwide where conditions are favorable for the rapid growth and accumulation of algae that produce toxins.
Mostly during the spring time in March though June, but they can occur at any time of year.
Tornadoes mostly occur in spring and early summer.
An algal bloom is a rapid increase or accumulation in the population of algae (typically microscopic) in an aquatic system. Algal blooms may occur in freshwater as well as marine environments. Typically, only one or a small number of phytoplankton species are involved, and some blooms may be recognized by discoloration of the water resulting from the high density of pigmented cells. Although there is no officially recognized threshold level, algae can be considered to be blooming at concentrations of hundreds to thousands of cells per milliliter, depending on the severity. Algal bloom concentrations may reach millions of cells per milliliter. Algal blooms are often green, but they can also be other colors such as yellow-brown or red, depending on the species of algae. Bright green blooms are a result of cyanobacteria (colloquially known as blue-green algae) such as Microcystis. Blooms may also consist of macroalgal (non-phytoplanktonic) species. These blooms are recognizable by large blades of algae that may wash up onto the shoreline. Examples of common harmful effects of HABs include:the production of neurotoxins which cause mass mortalities in fish, seabirds, sea turtles, and marine mammalshuman illness or death via consumption of seafood contaminated by toxic algaemechanical damage to other organisms, such as disruption of epithelial gill tissues in fish, resulting in asphyxiationoxygen depletion of the water column (hypoxia or anoxia) from cellular respiration and bacterial degradation
