1)
Go to the public version of the World Meteorological Organization’s that covers weather forcasts: https://worldweather.wmo.int/en/home.html
On the right side of the map that shows up, you can see two dark blue rectangle (they might say “please select” in the rectangles) that allow you to choose continents and countries. Pick any continent and then
any country of your choice. Then choose a city in that country and find the weather forecast. Now, some places don’t show a weather forecast, so you might have to choose a different country or even a different continent to get a forecast.
Repeat to find a total of four forecasts from around the world. Summarize your forecasts below:

While in the same webpage that you started off in in part a), find the WMO news and summarize
two articles below.
The World Meteorological Organization has issued a press release urging governments to protect radio frequencies allocated to Earth observation services, which are crucial for weather forecasts and long-term climate change monitoring. CGMS plenary has highlighted the need for the protection of radio frequencies for Earth observation satellites dedicated to monitoring weather, ocean, climate, and environment. The World Radiocommunication Conference, from 28 October to 22 November 2019, will make decisions that greatly impact Earth exploration, environmental monitoring, and meteorological satellite operation.
African heads of National Meteorological and Hydrological Services (NMHSs) have been reminded to utilize their knowledge from a WMO-sponsored Executive Training Programme to safeguard millions of people across the continent who are at risk of being affected by climate change.
2)
Go to noaa.gov
. a)
Report (write a paragraph) summarizing any recent news article of your choice. Some news articles are shown on the website’s initial page, while other articles are shown when you click on “news and features” in the blue section on the bottom. NOAA Fisheries has discovered a juvenile white abalone off the southern coast of California, one of only three live juveniles observed in natural subtidal reefs along the California coast in the past 20 years. The species, once in the millions, is now endangered and is one of NOAA Fisheries' Species in the Spotlight. The discovery indicates that the highly endangered species is reproducing in the wild, giving hope for successful recovery efforts in other areas. White abalone are ecologically, economically, and culturally important species, as their diet of kelp clears patches of rocky surface, increasing the diversity of fish and other animals that depend on kelp forest habitat. NOAA's white abalone recovery team, including about 20 partners, has placed over 12,000 captive-bred white abalone on native subtidal reefs since 2019. The species can live up to 40 years and reproduce only four to five times over their lives.

Go to Youtube and find weather reports/forecasts for each of the following. Describe the technology used at the time.
1970’s forcast
The technology used in weather reports and forecasts has changed dramatically over the past few decades. In the 1970s, weather reports were often based on information gathered by ground-based weather stations. This meant that forecasters had to rely on data that was sometimes inaccurate or incomplete. As a result, forecasts were often inaccurate.
1980’s forcast
In the 1980s, satellite technology began to be used more extensively in weather reporting. This allowed for more accurate data to be collected, which resulted in more accurate forecasts. However, satellite data was still sometimes inaccurate, and forecasters had to rely on other data sources as well.
1990’s forcast
In the 1980s, satellite technology began to be used more extensively in weather reporting. This allowed for more accurate data to be collected, which resulted in more accurate forecasts. However, satellite data was still sometimes inaccurate, and forecasters had to rely on other data sources as well.
In the 1990s, computer models began to be used more extensively in weather forecasting. This allowed for much more accurate forecasts, as computer models can take into account a wide range of data. Today, computer models are the primary tool that forecasters use to make predictions about the weather. Current forcast
In current forecasting we use things like Doppler Radar. Doppler radar detects all types of precipitation, the rotation of thunderstorm clouds, airborne tornado debris, and wind strength and direction. Weather Satellites monitor Earth from space, collecting observational data our scientists analyze. NOAA operates three types of weather satellites.
5)
Look in your text book and define the following old methods of forecasting. Also, for each of the
following, write an example of a statement a weather forecaster on TV might say that represents each method of forecasting. a)
Climatological forecasting:
Definition: A method of forecasting based on the statistical analysis of past weather conditions. Example statement:
b)
Trend forecasting:
Definition: A method of forecasting that uses past data to identify a pattern that is then used to predict future conditions.
Example statement: Based on the data, we expect the temperature to rise by 2 degrees over the next week. c)
Analog forecasting:
Definition: A method of forecasting that uses current weather conditions that are similar to past conditions to predict future conditions.

Explain the difference between GOES satellites and POES satellites. What is an advantage of each? What is a disadvantage of each?
GOES satellites are more expensive to manufacture and deploy than POES satellites, managed by
NESDIS. They consist of three operational spacecraft in geosynchronous orbit and a backup satellite. POES satellites have eleven satellites in sun-synchronous mode or a backup satellite ready for launch. GOES satellites offer high-resolution photos, real-time storm tracking, a greater field of vision, and a greater altitude for Earth observation. They are launched more regularly and are less expensive to launch
and maintain. However, GOES satellites have more energy requirements, require more frequent replacements, and can observe less of the Earth at once.
