Both, Weather and Climate are closely related with our daily experiences. While Weather is defined as short term variations of physical conditions (outdoor temperature, humidity, wind speeds, barometric pressure, sea surface temperature, cloudiness) surrounding us, Climate is defined as long term averages of above variations (usually at least 30 years). Decision making in modern societies goes nowhere without considering Weather and Climate. For South Florida, in particular, the link of Meteorology with health conditions and urban planning and development is really important. Namely, along these lines, Bio-Meteorology and Hurricane Science are two fields of great interest.
Bio-Meteorology covers the understanding of mechanisms of interaction between the natural physical environment and living things embeded within it, without taking them in isolation or as separate units. There are many interesting subjects to study in this field; however for South Florida, the study of environmental triggers of allergic reactions, how they spread out through the atmosphere, the incidence of Asthma and allergic respiratory disorders within floridians, and how asthma and allergies are linked to weather and climate trends represent very important health issues. As a matter of fact, the incidence of Asthma increased notably in the last ten years, and Florida did not escape from this trend.
Hurricane science is trying to understand mechanisms controlling both, the genesis and further dynamical evolution of hurricanes. For coastal areas the answer to these questions is crucial. In order to accomplish this goal, scientists use sophisticated numerical models based on hydrodynamic equations known as Navier-Stoke, along with the conservation of mass and energy. The resulting system of equations is highly nonlinear and needs a large computational power to produce accurate results. Coarse-grained effective medium toy models constitute an alternative to above mentioned models. These toy models consist of systems of differential equations less complicated than the Navier-Stoke. The positive side of this approach it is the availability and the possibility to see results that may be qualitatively in agreement with more accurate models.
Even though; the above mentioned research topics may appear somehow diverging, they are very tighly related regarding methods of Mathematical Physics used in computing quantities of interest. In both cases, methods borrowed from Physics of Complex Systems, and Dynamical Systems are applied in conjunction with techniques from Computational Physics.

Why it is important to study the Weather?
The Twentieth century has witnessed as never before how important their environmental problems are and it solutions for modern societies. Air pollution, environmental health, environmental toxicology, environmental forensics, global warming, high level of carbon mono- and dioxides in air, ozone hole and ozone layer depletion, water pollution, endangered species — these are some terms that appear with increasing frequency in the news. On the other hand, the education of the general public usually is not at the desired level producing either extremist positions or skeptic positions in the analysis of environmental issues, thus leaving open again and again the search for solutions to many of these problems.
Why we need to study the weather? It is there something practical we can gain from weather studies? The answer as you may expect is positive. We can gain a lot by studying the weather and understanding factors affecting specific weather conditions. Agriculture and clothe industries, urbanism, aviation and marine routes, environmental health, sport management and more, all depend on concrete weather conditions. But after all, what weather is? In popular words, weather is what you wear everyday. A further analysis, based on questions like what temperature is expected for today? Or is today going to be either sunny, or cloudy, or windy, or fogy, or raining?
Weather and climate play a major role in our lives. Weather, for example, often dictates the type of clothing we wear, while climate influences the type of clothing we buy. Climate determines when to plant crops as well as what type of crops can be planted. Weather determines if these same crops will grow to maturity. Nevertheless the most immediate effect is on our comfort. In order to survive the cold of winter and heat of summer, we build homes, heat them, air condition them, insulate them, only to find that when we leave our shelter, we are at the mercy of the weather elements.
Even when we are dressed for the weather properly, wind, humidity, and precipitation can change our perception of how cold and warm it feels. On a cold, windy day the effects of wind-chill tell us that it feels much colder than it really is, and if not properly dressed, we run the risk of frostbite or even hypothermia. On a hot, humid day we normally feel uncomfortably warm and blame it on the humidity. If we become too warm, our bodies overheat and heat exhaustion or heat stroke may result. Those more likely to suffer these maladies are the elderly with impaired circulatory systems and infants, whose heat regulatory mechanisms are not yet fully developed.
Weather affects how we feel in other ways, too. Arthritic pain is most likely to occur when rising humidity is accompanied by falling pressures. In ways no well understood, weather does seem to affect our health. The incidence of heart attacks shows a statistical peak after the passage of warm fronts, when rain and wind are common, and after the passage of cold fronts, when an abrupt change takes place as showery precipitation is accompanied by cold gusty winds. Headaches are common on days when we are forced to squint, often due to hazy skies or a thin, bright overcast layer of high clouds. Asthma attacks peaks during the passage of cold fronts and when spring is approaching. For some people, a warm dry wind blowing down-slope (a Chinook wind) adversely affects their behavior (they often become irritable and depressed).
