LAB 8 Amid the spatial and temporal variability of weather, patterns that emerge over longer periods of time constitute the   climate   of a region. Not only are average conditions important, but also  weather extremes and cyclical changes or oscillations are also included within   climatology   or  the study of climates. The study of   climate change   acknowledges that climates are not static  but have changed in the past due to natural factors and are projected to change in potentially  dramatic ways over the next century due primarily to the influence of humans on our  environment. Solving the puzzle of projecting future climate change means that we need to  understand how human influences fit into the natural systems that shape Earth’s climate. A   climograph   is a graph depicting monthly average weather information for a specific location.  Temperature and precipitation are graphed simultaneously on dual y-axes against the month of  the year on the x-axis. Precipitation is depicted with a bar graph that references the left y-axis  while temperature is depicted with a line graph that references the right y-axis. Apart from  providing the monthly average conditions, a climograph provides meaningful information on  seasonal changes through its graphic depiction, and this information can be informative of more  general environmental conditions as both temperature and precipitation are shown concurrently. Variations in climate across the Earth’s surface are a product of both global and more local- scale patterns of energy and moisture availability. Those factors recognized as most central to  climate are considered principle climate components and they include such factors as  insolation, temperature, pressure, air masses, and localized influences on precipitation. These  components are obviously interrelated as insolation input to the Earth system is a central  determining factor of temperature and temperature variations across the Earth’s surface drive  differences in air pressure. Underlying these principle climate components are fundamental  geographic factors including latitude, topography, continentality and the influence of ocean  currents on coastal   CONTINENTALITY Differences in the thermal properties of land and water influence the patterns of temperature a region experiences. Large bodies of water moderate temperature changes causing coastal areas to be warmer in the winter and cooler in the summer than continental regions. The proximity of a location to a large body of water also influences the supply of moisture made available through precipitation where wind direction allows.

"Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
