The direction of the rotational axis stays (nearly) fixed in space while the Earth orbits the Sun and the hemisphere that seems to “lean into” the Sun experiences summer, while the hemisphere that “leans away” from the Sun experiences winter.
Thus the tilt of the Earth’s rotation axis naturally explains why the seasons are opposite in the northern and southern hemispheres.
southern hemisphere “leans into” Sun summer in SH
summer in NH (leans into Sun)
northern hemisphere “leans away” from Sun winter in NH
winter in SH (leans away from Sun)
And six months later the opposite is true:

So what is the cause of the seasons?
The tilt of the Earth’s rotational axis,
and as a consequence of this tilt…
1) At different times of the year, the sun's
rays hit different parts of the globe more
directly.
Explain: 1) Slanting rays are spread out over
a greater area than vertical rays and are
therefore less concentrated. 2) Slanting rays
must pass through a greater thickness of
atmosphere than vertical rays and thus lose
more of their heat.

2) The days are longer in the summer than the winter.
Explain: The longer the sun is up, the more heat is gained from the sun
during the day than is lost at night.

Equinox and SolsticeA year on Earth can be split into four as we
complete our orbit of the Sun. Each of these
are marked by an equinox or solstice.
Solstices are the points when the tilt
towards or away from the sun is at the
maximum
Equinoxes are the two times of the year
when the Earth's axis is tilted neither
toward nor away from the sun, resulting in
a "nearly" equal amount of daylight and darkness at all latitudes.

Weather Maps are used to show the current state of the atmosphere and to forecast future conditions.
Weather maps describes day-to-day conditions in the atmosphere. Temperatures climb and drop, winds blow, rain and snow fall, and the sky is gray and cloudy or clear and blue. Meteorologists study today's weather and use it to predict what will happen tomorrow. Detailed weather maps display surface weather conditions over a wide area, providing a variety of information meteorologists use for their predictions.

Isolines (Iso means “same”) are lines on weather maps which represent patterns of pressure and temperature, wind and other information.

pressure, start low and go
up. Color all numbers within an interval of 4 of that number. For example
for the 992 isobar, color
992 and any value lower
(992-995).

Shortening and lengthening air pressure reading
To lengthen,
1. If number is less than 5, add a 10, 5 or greater add a 9
2. Add the decimal
3. Add the mb
Example:
103= 1010.3 mb
987= 998.7 mb
To shorten Barometric pressure:
1. Drop the 9 or 10
2. Drop the decimal
3. Drop the mb
Example:
1024.9 mb = 1024.9 mb
= 249
992.4 mb = 992.4 mb
= 992
